If one angle of a triangle is 60° and the other two angles are in the ratio 1 : 2, find the angles.

Given: one angle of triangle is 60°

Other 2 angles are in ratio 1:2

Formula Used/Theory:-

→ Angle sum property

Sum of all angles of triangle is 180°

1 angle is 60°

And other 2 angles are in ratio 1:2

The;

Let 2 angles x,2x

By angle sum property

60° + x + 2x = 180°

3x = 180° -60° = 120°

X = = 40°

The 2 angles of triangle are 40°;80°

Result:- The all 3 angles of triangle are 40°;80°;60°
