5:4:9
50:40:90
Answer:
50° and 40°
Step-by-step explanation:
Complementary angles sum to 90°
sum the parts of the ratio, 5 + 5 = 9 parts
divide 90 by 9 for the value of one part of the ratio
90° ÷ 9 = 10° ← value of 1 part of the ratio, thus
5 parts = 5 × 10° = 50°
4 parts = 4 × 10° = 40°
The 2 angles are 50° and 40°
