Angle B and Angle Y are equal and we already have A so:

angle B + angle A + angle C = 180
70 + 50 + angle C = 180
120 + angle C = 180
angle C = 60

Hope this helps :)

The answer is D) 60°

All angles in a triangle equal 180
°. Since these two triangles are the same, you just need to find the missing angle. 70+50 = 120

180 - 120 = 60


Hope this helps!
