If ∠AOC = (4x -16) and ∠BOC = 2(x + 20), Determine the value of x.

Answers

Answer:

x = 28

Step-by-step explanation:

4x-16 = 2(x+20)

4x-16 = 2x+40

Divide 2x from each side:

2x-16 = 40

Add 16 to each side:

2x = 56

Divide each side by 2:

What is a circle?

It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

The angle formed by two secants (lines cutting a circle at two places) intersecting outside the ring is half the distance between their arc minus the closest arc.

From the diagram, the equation is given as,

∠A = (arc DE - arc BC) / 2

∠A = (94° - 70°) / 2

∠A = 24° / 2

∠A = 12°

The measure of the angle ∠A will be 12°. Then the correct option is B.

Find f(g(2))+g(f(-1))

Answers

Answer:

-1

Step-by-step explanation:

First, we need to work out the left-hand side.

find g(2) → g(2) = 2 - 1 which is 1next, find f(1) → f(1) = 1³ which is 1

Now, we can work out the right hand side.

find f(-1) → f(-1) = -1³ which is -1then, find g(-1) → g(-1) = -1 - 1 = -2

Finally we can work out the full sum: 1 + -2 = -1.

Find x

3(x) + 13 = 5(x) + 93(x) - 5(x) = 9 - 13-2(x) = -4x = 2

Then find m∠A

3(x) + 13°3(2) + 13°6° + 13°19°

Answer:

19°

That's your answer

Step-by-step explanation:

So In this problem We are told both angles are vertical. That is enough information. When 2 Angles are vertical they measure the same. Vertical angles have SAME measure.

Now we are given 2 angles.

Angle A and Angle B

Angle A= (3x+13) degrees

Angle B=(5x+9) degrees

Knowing that and that they measure the same just put them equal to each other……

3x+13=5x+9

Given the equation just solve…..

Lets subtract 9 from 13

Then Subtract 3x

Then Divide by 4

3x+13=5x+9

3x+4=5x

4=2x

x=4/2 =2

x= 2

We now Know X is equal to ½ but we still need to figure out the measure of angle A

Angle A= 3x+13

So just plug in

3(2) +13= 19° :)

Identify the solution to the system of equations
{x=-2y-6 -3x-7y=18

Answers

Answer:

(- 6, 0 )

Step-by-step explanation:

x = -2y - 6 → (1)

- 3x - 7y = 18 → (2)

substitute x = - 2y - 6 into (2)

- 3(- 2y - 6) - 7y = 18 ← distribute parenthesis and simplify left side

6y + 18 - 7y = 18

- y + 18 = 18 ( subtract 18 from both sides )

- y = 0 , then

y = 0

substitute y = 0 into (1)

x = - 2(0) - 6 = 0 - 6 = - 6

solution is (- 6, 0 )

Answer:

  (x, y) = (-6, 0)

Step-by-step explanation:

A system of equations is easily solved using a graphing calculator. The attached shows the solution to be ...

  (x, y) = (-6, 0)

__

The first equation gives a convenient expression for substituting for x in the second equation:

  -3(-2y -6) -7y = 18

  18 -y = 18 . . . . . . . . simplify

  y = 0 . . . . . . . . add y-18

  x = -2(0) -6 = -6

The solution by substitution is (x, y) = (-6, 0).

Instructions: Given the figure, what is the angle of rotational symmetry?

Answers

Answer:

Step-by-step explanation:

The Angle of Rotational Symmetry is the degree of rotation required to make the shape look like the original.

However, if you rotate it again by 90°, it looks identical to the original.

90° + 90° = 180°

What is the mean of 75,14,48,81,39,67,33,19

Σarray/arraysize = 75+14+48... / 8

Answer:

Mean = 47

Step-by-step explanation:

Given terms :

7514488139673319

The mean is equal to the sum of the terms divided by the number of terms.

Therefore, the mean is equal to :

75 + 14 + 48 + 81 + 39 + 67 + 33 + 19 / 8 [Take terms that add up to 100, makes it easier to calculate!]100 + 100 + 89 + 87 / 8200 + 176 / 8376/8Mean = 47

What to do: Complete each of the following problems involving ladders and walls by using trigonometric functions and inverse trigonometric functions to determine unknown lengths and angle measures.


Questions:

a) A ladder is placed against the wall of a building such that the bottom of the ladder is 3 ft from the bottom of the wall. If the ladder forms a 14 degree angle with the building, how high up the wall does the ladder reach?


b) A 15 foot ladder is leaned against a wall so that the bottom of the ladder forms a 75 degree angle with the ground. How far up the wall does the ladder reach?


c) You need to paint shutters on a window that is on the second floor of your house. You have a 20 foot ladder that you will use. There is a warning on the ladder that states the angle formed by the ladder and the ground must not be less than 70 degrees, or the ladder may slip and cause serious injury or death. You planned on placing the bottom of the ladder 3 feet from the base of the house.

Will the angle formed between the ground and the ladder be safe? What is the furthest possible distance the ladder can be placed to maintain a safe angle?

Answers

Answer:

Step-by-step explanation:

a) x be the height of the wall

[tex]tan \ 14 =\dfrac{opposite \ side}{adjacent \ side}\\\\\\0.2493 = \dfrac{3}{x}\\\\\\x*0.25 = 3\\\\x = \dfrac{3}{0.25}\\\\\\x = 12 ft[/tex]

b) Let y be the hieght of  the wall

[tex]Sin \ 75 = \dfrac{opposite \ side}{hypotenuse}\\\\\\0.9659 = \dfrac{y}{15}\\\\\\0.97*15=y\\\\[/tex]

y = 14.6 ft

c) Let the angle formed between the bottom of the ladder to the ground be 'x'

[tex]Cos \x =\dfrac{adjacent \side}{hypotenuse}\\\\Cos \ x =\dfrac{3}{20}\\\\\\Cos \x = 0.15\\\\x = Cos^{-1} \ (0.15)\\\\[/tex]

x = 81°

No, the angle formed between the ground and the ladder is not safe as it is more than 70°

Let the farthest possible distance ladder placed from the wall be 'y'

[tex]Cos \ 70 =\dfrac{adjacent \ side }{hypotenuse}\\\\0.342 = \dfrac{y}{20}\\\\0.3*20=y[/tex]

y = 6 ft

6 ft is the furthest possible distance the ladder can be placed to maintain a safe angle.
