Answer:

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

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°
