These are vertical angles, this means that they are equal to each other. Set them equal to eachother and solve for x:

3x + 20 = 5x - 16

(3x - 3x) + 20 = (5x - 3x) - 16

20 + 16 = 2x + (- 16 + 16)

36/2 = 2x/2

x = 18

Hope this helped!

Answer:

x = 18

Explanation:

Since they are vertical angles, the two angles must be congruent.

So, 3x + 20 = 5x - 16

Isolate x: 2x = 36

Divide: x = 18
