Question

Tell whether the angles are adjacent or vertical. Then find the value of x.

Answer 1

111/3 = 37

Explanation:

The angles shown are "vertical" angles. Thus, 107° = (3x - 4), and

107 = 3x - 4, so that

111 = 3x, and:

x = 111/3 = 37

Answer 2

They are vertical. x=37 degrees

Explanation:

If two lines form an x, then it's a vertical angle.

3x-4=107

3x=111

x=37
