Question

Three angles are in the ratio 2:5:4 whose measures add up to 180°. Find the angles.​

Answer 1

Step-by-step explanation:

let angles are x

then angle's ratio =2x:5x:4x

2x+5x+4x=,180° (Given above)

11x=180°

x=180/11

angles : 2x=2×180/11= 32.72° approx.

5x=5×180/11=81.81° approx.

4x= 4× 180/11=65.45° approx.

(for check 32.72°+81.81°+65.45°=179.98°approx.)
