Question

Angle A has a measure of 3x° and angle B has a measure of x+22°. If angles A and B are complementary, what is the value of x? *

Answer 1

Answer: x = 17

Step-by-step explanation: combine all of those numbers.

3x+x+22.

Combine like terms, so

4x + 22 = 90 (90 is the sum of 2 complementary angles)

Subtract 22 from both sides to get

4x = 68

Now divide by 4 to get x which is

x = 17
