Question

Two angles are vertical if one is 5x - 15 and the second angle is 3x + 1, what is the value of x

What is the measure of each angle

Answer 1

Explanation:

If they are vertical angles, they are opposite to each other where two lines intersect. Vertical angles are equal to each other so

5x-15=3x+1

2x-15=1

2x=16

x=8 degrees.

The angles are

a=5x-15, and x=8 so

a=5(8)-15

a=40-15

a=25 degrees.
