Answer:   12. x =7           13. x =6

Step-by-step explanation:

Both angles in the triangle has to equal to each other because they are both equivalent.

Set both expressions equal to each other and solve for x.  

12.  5x =  35    Divide both sides by 5

x =  7  

13.     3x =   5x - 12      Subtract 5x from both sides

        -5x       -5x  

   -2x =  -12      Divide both sides by -2

 x = 6
