Angle 1 = 33°, angle 2 = 52° (option C)

Step-by-step explanation:

The triangle by the left:

31° + 116° + ∠1 = 180° (sum of angles in a triangle)

147° + ∠1 = 180°

∠1 = 180° - 147°

∠1 = = 33°

The triangle by the right:

38° + 90° + ∠2 = 180° (sum of angles in a triangle)

128° + ∠2 = 180°

∠2 = 180 - 128

∠2 = 52°

Angle 1 = 33°, angle 2 = 52° (option C)
