2x + 1 = -15

Subtract (1) from both sides.

2x = (-15-1)

2x = -16

Divide both sides by (2) so that (x) is by itself.

x = -8

Hi!

<u>Your answer is 52.</u>

To start off, let's start with some facts that will help us solve this:

<u><em></em></u>

<u><em>Supplementary angles</em></u> are two angles whose angle measures add up to 180 degrees. You can know that they are supplementary because they can be connected by a straight line.

<u><em>Triangles (all of them)</em></u> have angles that add up to 180 degrees.

We can start by using supplementary angles to solve. See where the angle of 67 degrees is? The one to the right of it is supplementary to it since they are on a straight line. That means their sum adds up to 180 degrees:

67 +?=180

?=113

That angle is 113 degrees.

Now, we have 2 out of 3 angles in the triangle. Since we know that triangles' angles add up to 180 degrees, we can make an equation:

15+113+x=180

128+x=180

x=52

Therefore, x is equal to 52.

The area (A) of a circle with a radius of r is given by the formula and its diameter (d) is given by . Arrange the equations in
ella [17]

Answer:

see explanation

Step-by-step explanation:

A = πr² ← r is the radius and r = \frac{1}{2} d ← d is the diameter

Hence

π (\frac{1}{2} d)² = A, that is

\frac{d^2\pi }{4} = A ( multiply both sides by 4 )

d²π = 4A ( divide both sides by π )

d² = \frac{4A}{\pi } ( take the square root of both sides )

d = \sqrt{\frac{4A}{\pi } }

Since A and B are parallel lines, the two marked angles are congruent.
Then, 2x + 12 = x + 25
We can solve for x:

What is the slope and Y intercept of the equation X=10
xenn [34]

Answer:

Slope is undefined and y int does not exist

Step-by-step explanation:

x=10 means it will be a vertical line where x= 10 so the slope is undefined and since it is perfectly vertical, it will never touch the y axis.
