Question

If angleA and angleB are complementary, and angleA = 19°, what is the measure of angleB?

Answer 1

angle B = 71 degrees

Explanation:

If angle A and angle B are complementary, and angle A = 19°, what is the measure of angle B?

complementary angles summed together equal 90 degrees so:

angle B = 90 - 19

angle B = 71 degrees
