Question

The ratio of two angles is 3:1 find the 1) larger angle if the smaller is 180 degree. 2) smaller angle if the larger is 63 degree?

Answer 1

Answer:

1) If smaller angle is 180° then larger angle is 540°

2) If larger angle is 63° then smaller angle is 21°

Step-by-step explanation:

Given ratio of two angles is 3:1

Let one angle = 3x ,

second angle = x

Case 1:

If smaller angle = 180°

=> x = 180°

Larger angle = 3x = 3 × 180° = 540°

Case 2:

If larger angle = 63°

=> 3x = 63°

/* Divide both sides by 3, we get

=> x = 21

Smaller angle = x = 21°
