Question

the complementary angles are in ratio 1:4 then the angles are_____​

Answer 1

Answer:

let the angles are= x and 4x

complementary angles are sum up to 90°.

x+4x=90°

5x=90°

x=90°/5

x=18°

x=18°

4x=4(18)

4x=72°

angles are 18°and 72°

Answer 2

Answer:

let 1:4 be x and 4x

x + 4x = 90°..................(angles are complementary)

5x = 90°

x = 90°/5

x = 18

x = 18°

4x = 4 × 18

= 72°

the angles are 18° and 72°
