    The measures of the two angles are 34° and 56°

    Step-by-step explanation:

    * Lets explain how to solve the problem

    - The complementary angles are the angles whose the sum

    of their measures is 90°

    - The measure of one angle is six more than half the measure

    of another angle

    - Let the measure of the second angle angle is x

    ∵ The measure of the 2nd angle is x

    ∵ The measure of the first angle is 6 more than the half of the

    measure of the second angle

    ∴ The 1st angle is 6 + 1/2 x

    ∵ The two angles are complementary

    ∴ The sum of their measures is 90°

    ∴ x + (6 + 1/2 x) = 90

    ∴ (x + 1/2 x) + 6 = 90

    ∴ 3/2 x + 6 = 90

    - Subtract 6 from both sides

    ∴ 3/2 x = 84

    - Multiply both sides by

    ∴ 3x = 168

    - Divide both sides by 3

    ∴ x = 56

    ∵ x is the measure of the 2nd angle

    ∴ The measure of the 2nd angle is 56°

    ∵ The measure of the 1st angle = 6 + 1/2 x

    ∵ x = 56

    ∴ The measure of the 1st angle = 6 + 1/2 (56) = 34°

    * The measures of the two angles are 34° and 56°
