Answer:
48 degrees
Step-by-step explanation:
<u>1) Solve for x</u>
Complementary angles add up to 90 degrees. Therefore, m<A + m<B is equal to 90:

Open up the parentheses

Subtract 20 from both sides

Divide both sides by 5

Therefore, x is equal to 14.
<u>2) Determine angle A</u>

Substitute x with 14

Therefore, the measure of angle A in degrees is 48 degrees.
