Answer:
x = 14
Step-by-step explanation:
Knowing that this figure is a vertical angle.
Define vertical angles ⇒ a pair of opposite angles formed by intersecting lines
Thus, if the left side = 122
then the other side must equal 122
The equation is:
8x + 10 = 122
Subtract 10 from both sides
8x + 10 - 10 = 122 -10
8x = 122
Divide both sides by the same factor
8x/8 = 122/8
Simplify
x = 14
Thus, x = 14.
