We are given two angles in each triangle. We can solve for the missing angles. In the upright triangle, the missing angle is 180-50-60=180-110=70. In the upside down one, the missing angle, x, is 180-50-70=180-120=60. Notice than 70 degrees, x, and y form a straight line which is 180. Then y is 180-70-60=180-130=50.
