Answer:
x=8

Explanation: Because they are opposite angles, they can be assumed to be equal to each other. Therefore, you can set the two equations equal to each other, creating
9x+72=4x+112, and from there you can subtract
4x as well as
72 from both sides to get
5x=40. Then, divide both sides by
5 to get
x=8.

Answer:

x =8

Explanation:

The angles are vertical angles which means they are equal

4x+112 = 9x+72

Subtract 4x from each side

112 = 5x+72

Subtract 72 from each side

40 = 5x

Divide each side by 5

40/5 =x

8 =x
