Answer 1

x=16....................................................

Answer 2

x = 16

Explanation:

The angles shown are vertical angles

Vertical angles are congruent ( equal to each other )

Thus, 85 = 4x + 21

( we now solve for x )

85 = 4x + 21

step 1 subtract 21 from each side

21 - 21 cancels out

85 - 21 = 64

we now have 64 = 4x

step 2 divide each side by 4

64 / 4 = 16

4x / 4 = x

we're left with x = 16
