Answer:

x=14, angle= 128 degrees

Step-by-step explanation:

The two angles are equal to each other so you can set the equations equal.

7x+9=9x-19

Now solve for x:

28=2x

x= 14

Plug 14 back into an equation, so 7(14)+9=128 degrees.












The answer is 14. you sent the equations equal to each other.
