Mr. Hanson assigned his students a trigonometry project. Each student was to use a clinometer to determine the angle of elevation to the sun followed by trigonometry to determine the length of their shadows. James and Andy were partners in this assignment. James stood tall and Andy found that the distance from the ground to the clinometer that James was holding was 5.5 feet. James determined the angle of elevation to the sun to be 35 derajat. Draw a picture and write an equation to model this scenario. Then solve for the variable without using your calculator (hint: you should still have a trig function in your answer).

The answer for lateral surface area of the Triangular prism is 180 cm²

Any solid object's lateral area can be calculated using the lateral area formula. Any figure's lateral area only includes the non-base faces. Calculating the lateral surface area of various forms, such as the cuboid, cube, cylinder, cone, and sphere, is made easier using lateral area formulas.

The lateral area for a triangular prism

A triangular prism's lateral area is equal to the sum of its side faces' areas (which are 3 rectangles). Specifically, it is the total surface area less the surface areas of the two bases. Additionally called the lateral surface area (LSA). Due to the two dimensions involved in its calculation, we measure it in square units.

The total of the three regions is the triangular prism's lateral area. Consequently, the triangular prism's lateral area formula is

Triangular prism lateral surface area (LSA) = ah + bh + ch (or) (a + b + c) h.

We are aware that the perimeter of the base is (a + b + c) (triangle). Hence,

Triangular prism's lateral surface area (LSA) is equal to the product of the base's perimeter and the prism's height.

base perimeter × height

Explanation

The Given Image of the solid is Matching to a prism.so we are calculating the lateral surface area of the prism

The dimensions of each base are:

a = 5cm

b = 4 cm

c = 3 cm

The height of the triangular prism = 15cm.

Thus, the lateral area of triangular prism = (a + b + c ) h

= (5 + 4 + 3) 15

= (12) 15

= 180 cm²

Answer: The lateral area of the given triangular prism = 180 cm²

The number of dimes more than nickels in the jar is 17.

The first step is to determine the total number of coins in the jar.

Total number of coins in the jar = (sum of ratios x number of quarters) / ratio that represents the number of quarters

Sum of ratios = 2 + 3 + 5 = 10

Total number of coins in the jar = (10 x 85) / 5 = 170

Number of dimes in excess of nickels = [(ratio representing dimes - ratio representing quarters) / sum of ratios) x total number coins

The value of x is -20 and can be calculated using basic proportionality theorem.

The Basic Proportionality Theorem, often known as the Thales Theorem, was developed by the well-known Greek mathematician Thales.

Basic Proportionality Theorem asserted that the ratio of any two related sides is always the same for any two equiangular triangles.

Thales provided the basic proportionality theorem based on this idea (BPT). Similar triangles have introduced this idea before. If two triangles resemble one another, then

The corresponding angles of both triangles are equal.

The corresponding sides of both triangles are proportional to one another.

Since the ratio of other side pair is 1:1, similarly 4x+20 = 3x

A point with 'x' and 'y' coordinates are given by:

d=|Ax*+By*+C|/√(A²+B²)

In this issue, the path's line includes:

When x = 0, and y = 0, the intercept is 0.

0.5 slope means that when x rises by 4, y rises by 2.

or, -x+2y=0

The coefficients of the line are:

A=-1 and B=2

Coordinates of the giant pumpkin is (x*,y*)=(-4,-3)

The distribution of z-scores would be a normal distribution centered at 0, with a standard deviation of 1.

The distribution of time it takes for people to solve a certain Sudoku puzzle is strongly skewed to the right. This means that most people take a shorter amount of time to solve the puzzle, but some take a longer amount of time. The mean (average) of this distribution is 30 minutes and the standard deviation is 15 minutes.

To find the distribution of z-scores, we need to convert the times into z-scores, which is done by subtracting the mean (30) from each time and then dividing by the standard deviation (15). This gives us a new distribution of z-scores, which is centered at 0 (since the mean of the times was subtracted from each time) and has a standard deviation of 1.

The values of x and y that makes the figure a parallelogram are x = 17 and y = 26

A parallelogram is a four-sided geometric shape that has opposite sides that are parallel to each other.

The opposite sides of a parallelogram have the same length, and the opposite angles are also equal. The opposite sides of a parallelogram are also known as the bases, and the other two sides are known as the legs.

Since the opposite sides of a parallelogram are equal in length, we can say:

3x + 6 = 4 - x

3x + x = 4 - 6

4x = -2

x = -2/4

x = -1/2 = -0.5

y + 2 = 2y - 3

2 + 3 = 2y - y

5 = y

y = 5

Likewise, the opposite angles of a parallelogram are equal, so we can say:

(4x - 12)° = (3x + 5)°

4x - 12 = 3x + 5

4x - 3x = 5 + 12

x = 17

(3y + 46)° = (5y - 6)°

3y + 46 = 5y - 6

46 + 6 = 5y - 3y

In the triangle, we will use the Law of Cosines to find the value of angle q. angle q in the triangle is approximately 61.2° (rounded to one decimal place).

The Law of Cosines is a mathematical formula used in trigonometry to find the length of a side or an angle in a triangle.

The formula can be used to find the length of a side or an angle in a triangle, given the length of the other sides and angles.

The Law of Cosines is particularly useful when only two sides and the angle between them are known, or when only two angles and the side between them are known.

To use the Law of Cosines, you need to identify the sides and angles that you know and plug them into the formula. Then, you can use algebra to solve for the unknown side or angle.

The Law of Cosines is related to the Pythagorean Theorem, which states that in a right triangle, the sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the longest side.

The Law of Cosines can also be used in three-dimensional geometry to find the distance between two points in space.

The Law of Cosines is a useful tool in many fields, including engineering, physics, and computer graphics, and is widely used in solving geometric problems.

In this triangle, we have x = 66.1 cm, y = 22.8 cm, and angle f = 23.3º. We want to find angle q, which is opposite side x.

We can use the Law of Cosines to find the value of cos(q), and then use the inverse cosine function to find the value of q in degrees.

cos(q) = (x² + y² - x²)/(2xy)

cos(q) = (66.1² + 22.8² - 22.8²)/(2 * 66.1 * 22.8)

cos(q) = 67.8664/150.6448

cos(q) = 0.449

q = cos⁻¹(0.449)

q = 61.2°

Therefore, angle q in the triangle is approximately 61.2° (rounded to one decimal place).

Answer:

In a right triangle, the angle opposite the hypotenuse (side c) is always 90 degrees, so we can use the trigonometric function sine to find the length of side c.

sin(A) = opposite / hypotenuse

sin(50) = b / c

so c = b / sin(50)

c = 13 m / sin(50)

c ≈ 22.361 m

So the length of side c is approximately 22.361 meters

This means x = 5a pairs up with y = 0.

=========================================================

Explanation:

The two lines have the same x-intercept, which means they cross the x axis at the same location. This is the solution to the system since this point is on both lines simultaneously.

To find the x-intercept, plug in y = 0 and solve for x.

(1/5)x+4y = a

(1/5)x+4*0 = a

(1/5)x = a

x = 5a

We don't know the value of 'a', so we cannot determine the numeric value of x.

The x-intercept is located at (x,y) = (5a,0) and this is the solution to the system.
