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?

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

step-by-step explanation:

first you will have to convert 3/4 into a decimal

which is .75

then you will have to divide 1.5 by .75

which is 2

no you have to divide

560

hope this : )
