Aim:

We need to find the angle C and sides c and b.

Explanation:

Use sine law.

Substitute A = 50°. B = 45°, and a=3 in the equation.

Use the triangle sum property to find the angle C.

Substitute A = 50°. and B = 45° in the equation.

Substitute A = 50°. C= 85°, and a=3 in the equation.

Final answer:

Question:

Solution:

Remember the following theorem: the ratio of the areas of two

similar triangles is equal to the ratio of the squares of their corresponding sides. Then, here A1 and A2 are areas of two similar triangles, and S1 and S2 are their corresponding sides respectively :

S1 : S2 = 5 : 8

then

now, A1 = 87.5. Thus, according to the theorem, we get the following equation:

this is equivalent to:

by cross-multiplication, this is equivalent to:

solving for A2, we get:

so that, we can conclude that the correct answer is:

The area of the larger triangle is

The expression has a value of -31 when a = 2 and b = –3

From the question, the expression is given as

5 – a(3² + (ab + 2)² – 7)

Also, we have the values of the variables to be

a = 2 and b = –3

Substitute a = 2 and b = –3 in the expression 5 – a(3² + (ab + 2)² – 7)

So, we have the following equation

5 – a(3² + (ab + 2)² – 7) = 5 – 2 * (3² + (2 * -3 + 2)² – 7)

Evaluate the expressions in the bracket

5 – a(3² + (ab + 2)² – 7) = 5 – 2 * (3² + (-4)² – 7)

Evaluate the exponents

5 – a(3² + (ab + 2)² – 7) = 5 – 2 * (9 + 16 – 7)

So, we have

5 – a(3² + (ab + 2)² – 7) = 5 – 2 * 18

This gives

5 – a(3² + (ab + 2)² – 7) = 5 – 36

Evaluate the difference

5 – a(3² + (ab + 2)² – 7) = -31

Hence, the value of the expression is -31

The sides of the triagle have lengths:

1.1 p + 9.5 q

4.5 p - 5.2 r

5.3 r + 5.4 q

Or:

1.1 p + 0 r + 9.5 q

4.5 p - 5.2 r + 0 q

0 p + 5.3 r + 5.4 q

If we want to calculate the perimeter of the triangle, we just need to sum the three lenghts:

(1.1 + 4.5) p + (-5.2 + 5.3) r + (9.5 + 5.4) q

= 5.6 p + 0.1 r + 14.9 q

A(-4, 0) and B(4, 0)

A parabola is symmetrical about the y-axis, if the vertex is of the form (0, y). The y-axis is the line of symmetry. That is, the point x = 0.

If the parabola is symmetric about the y-axis, points A and B should fall on opposite sides of the y-axis.

For the parabola to be symmetric about the y-axis, the possible points to move A and B to are A(-4, 0) and B(4, 0)

The equation for 'P', representing Madeline's total pay on a day on which she sells 'x' computers is → P = 80 + 20x.

Given, At an electronics store, Madeline sells computers as a salesperson. She receives a $80-per-day base salary in addition to a $20 commission for each computer she sells.

What is Equation Modelling?

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We can model the equation for Madeline's total pay as follows -

P = base pay + (number of sold computer) × (cost of 1 computer)

P = 80 + 20x

Therefore, the equation for 'P', representing Madeline's total pay on a day on which she sells 'x' computers is → P = 80 + 20x

The dimensions of new rectangular playing field are 183 yards and 44 yards, by the concept of perimeter of rectangle.

The whole distance that the sides or limits of a rectangle cover is known as its perimeter. Since a rectangle has four sides, its perimeter will be equal to the sum of those four sides. Given that the perimeter is a linear measurement, the rectangle's perimeter will be expressed in meters, centimeters, inches, feet, etc.

Formula, perimeter of rectangle =2× (length +width)

Given, perimeter of rectangular playing field = 454 yards (equation 1)

Let us assume, width =x

According to question length = 4x+7 (quadruple=4times)

By the above equations,

Perimeter=2×(4x+7+x)

2×(5x+7) =454 (by equation 1)

Dividing the above equation by 2 both the sides

(5x+7) =227

Subtracting the above equation by 7 both the sides

5x=220

Dividing the above equation by 5 both the sides

x=44

Therefore, the required width of new rectangular playing field is 44 yards and length of new rectangular playing field is 183 yards

The measure of angle 1 is 71º, we can find this, because angle 1 and angle x form a straight line of 180º, so 180º - 109º = 71º

The measure of angle 2 is also 71º, we can use the vertical angles propierty, then m∠1 = m∠2

The measure of angle 3 is 109º, we can use again the vertical angles theorem to find that m∠x = m∠3

Themeasure of angle 7 is 109º. We need to use the alternating exterior angles theorem. Since angle x and angle 7 are not between the parallel lines they're exterior angles; and since they're on opposite sides of the transversal line, they're alternates. Then the theorem says that m∠x = m∠7

The measure of angle 6 is 71º, again we're using the fact that angle 7 and angle 6 forms a straight line, then m∠6 = 180º - 109º = 71º

Now we can find the lasts two measures using the vertical angles theorem.

The measure of angle 5 is 71º, because m∠6 = m∠5

The measure of angle 4 is 109º, because m∠7 = m∠4

1 counsellor for every 9 campers.

Lets' determine the type of variation and write the equation.

Here, we can see that for every 9 campers, there is one extra counsellor. This means that as the number of campers increase, the number of counsellors will also increase.

Since one variable as the other increases, this is a direct variation.

Hence, we have the equation which represents the direct variation below:

y = 9x

Where x represents the number of counsellors and y represents the number of campers.

The Pythagoras theorem gives the relation for the right-angle triangle between the perpendicular, base, and hypotenuse thus the perpendicular x will be 14.70.

A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices.

Triangle is a very common figure to deal with in our daily life.

In a triangle, the sum of all three angles is 180°

As per the given right-angle triangle,

Pythagoras' theorem states that in a right-angle triangle →

Hyp² = Perp² + Base²

In the given triangle Hyp = 21 , Base = 15 and Perp = x

So,

21² = x² + 15²

x² = 21² - 15²

x = √216 = 14.6993 ≈ 14.70
