Question

Angle A and angle B are complementary
The measure of angle A is (5x + 15)°
• The measure of angle B is 30°
What is the value of x?​

Answer 1

Answer:

Step-by-step explanation:

∠A + ∠B  = 90°  {given they are complementary}

5x+ 15 + 30 = 90

5x + 45 = 90

5x = 90 - 45

5x = 45

x = 45/5

x = 9
