Two complimentary angles are in the ratio 4:5. find the angle

40 degrees and 50 degrees because it will change by the ratio

40° and 50°

Step-by-step explanation:

Sum the parts of the ratio, 4 + 5 = 9 parts

Complementary angle sum to 90°

Divide 90° by 9 to find the value of one part of the ratio

90 : 9 = 10° ← value of 1 part, thus

4 parts = 4 * 10° = 40°

5 parts = 5 * 10° = 50°

The angles are 40° and 50°
