Question

if two complementary angles are in the ratio 1:8 find their angles​

Answer 1

Answer:

First angle = 10°

Second angle = 80°

Step-by-step explanation:

Let the angles be x and 8x.

$x + 8x = 90 \\ 9x = 90 \\ x = 90 \div 9 \\ x = 10$

Therefore, first angle = x = 10°

first angle = x = 10° second angle = 8x = 80°

Answer 2

Answer:

10° and 80°

Step-by-step explanation:

according to the ratio, let the complementary angles be 1x and 8x

1x +8x = 90°

9x = 90°

x = 10°

1x = 1 × 10° = 10°

8x = 8 × 10° = 80°
