Answer:
Y is fairly simple to understand. Since theres a square on that angle, you can automatically tell that its a right angle. Right angles are angles that are 90 degrees, and are usually shaped like an L.
To determine the angle, we subtract 49 and 90 from 180, since the entire angle is leveled over a 180 plane.
180-49-90 = 41
X = 41 and y = 90.
