Answer:
angle 1 = 56°
angle 2 = 56°
angle 3 = 74°
Step-by-step explanation:
angle 1 - all angles in a triangle should add up to 180:
66 + 58 = 124
180 - 124 = 56
angle 2 - angles across from each other are the same measurement
angle 3 - apply the rule from angle 1 and use angle 2:
56 + 50 = 106
180 - 106 = 74
