Answer:
So, we know that since the angles are going to be the same, we can create a equation out of it.
Step-by-step explanation:
7x+9=9x-19
After this, move all x's to one side and all other to another side. Make sure to switch if it is positive or negative.
19+9=9x-7x
28=2x
28/2=2x/2
x=14.
Now that we have X, we have to plug it back in to the problem. You can choose whichever one you want
(7*14)+9=107.
107 degrees is the solution for the angle.
