Answer:
60° and 30°
Explanation:
Complementary angles sum to 90°
sum the parts of the ratio, 6 + 3 = 9 parts
Divide 90° by 9 to find the value of one part of the ratio.
90° ÷ 9 = 10° ← value of 1 part of the ratio, then
6 parts = 6 × 10° = 60°
3 parts = 3 × 10° = 30°
The measure of the angles is 60° and 30°
