u
X +86
1. What is the relationship between the angles identified?
They are
angles.
2. Set up the equation needed to find 2.
3. Find the value of x.

Answer 1

x=24

Explanation:

By the vertical angles theorem all vertical angles are congruent. So 4x-10 is equal to 86.

4x-10=86 ------> Add 10 to both sides

4x=96 --------> Divide 4 by both sides

x=24
