Answer:

180˚ or C

Step-by-step explanation:

Complementary angles are two angles that add up to 90˚.

Since m∠A = 40˚ then we can write and equation where ∠B equals x.

40 + x = 90

40 - 40 + x = 90 - 40

x= 50

m∠B = 50˚

Supplementary angles are two angles that add up to 180˚.

Since ∠B is the supplement of ∠C, we will use x as the value of ∠C.

50 + x = 180

50 - 50 + x= 180 - 50

x= 130

So ∠C = 180˚

Thus, 50˚ + 130˚ = 180˚
