Answer:
X - 90 degrees
Y - 43 degrees
Step-by-step explanation: When you fold over the triangle to reflect you get 47 degrees as angle C. Then, because X is a perfect right angle it is 90 degrees. Then you add 47 and 90 and get 137, then subtract that from 180 because all the angles within a triangle should eqaul up to 180 degrees.
