Question

if one angles of a triangle is 60 and the other two angles are in the ratio 1:2,find the angles​

Answer 1

Step-by-step explanation:

Let the first angle be x° .

And, second angle = 2x°

Third angle = 60° [given]

A/q,

x° + 2x° + 60° = 180°

3x° + 60° = 180°

3x° = 180° - 60°

3x° = 120°

x° = 120°/ 3

x° = 40°

Hence, first angle = x° = 40°

second angle = 2x° = 2 × 40° = 80°
