Answer: 12. x =7 13. x =6

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
