x = 8
Step-by-step -e-x-p-l-a-n-a-t-i-o-n- below
The angles shown are vertical angles
Vertical angles are congruent (equal to each other)
This means that 8x + 36 = 5x + 60
Using this equation we can solve for x
8x + 36 = 5x + 60
==> subtract 36 from both sides
8x = 5x + 24
==> subtract 5x from both sides
3x = 24
==> divide both sides by 3
x = 8
