Question

PLEASE HELP***
solve for x

Answer 1

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 2

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
