Answer:
Explanation:
we are told that JK and KL sides are the same (b/c of the marks) so set them equal and solve for x
8x = 13x-15
8x - 8x + 15 = 13x - 8x -15 + 15
15 = 5x
divide by 5
3 = x
Use the fact that it's 180° around the interior angles of the triangle to solve for y
180 = 5y -3 + 52 + 76
52 = 5y - 3
55 = 5y
11 = y
