    27 degrees

    Step-by-step explanation:

    Complementary angles means that both angles add up to 90 degrees. So, first, you should find the value if x by setting the sum of angle A and angle B to 90. You should get x = 8. Then, substitute 8 for x in the equation for the measure of angle A, and you will get 27 degrees.
