Answer ASAP

angle A and angle B are complementary angles. The measure of angle A is (3x)"
and the measure of angle B is 45°. What is the value of x?

Answer 1

Answer:

x = 15°

Step-by-step explanation:

Complementary angles are two angles whose sum = 90°

∠A + ∠B = 90°

3x + 45 = 90

3x = 45

x = 45/3

x = 15°
