Answer:

I don't think your supposed to find the value of x and y but I think you need to combine like terms.

The two triangles bare congruent, so we know that the interior angles of the triangles are the same. So:

11x - 4 = 117

11x = 121

x = 11

Do the same thing with the corresponding sides to solve for y:

17y - 8 = 12 + 13y

4y = 20

y = 5
