Question

Set
1. The angles of a triangle are in the ratio
2:3 of the third
angle is 50', Find the
other two angles.​

Answer 1

let the angles of triangle be 2x and 3x

2x + 3x+ 50 = 180 ( angle sum property)

5x + 50 = 180

5x = 180 - 50

5x = 130

x = 130/ 5

x = 26

therefore angles are

2 × 26 = 52°

3× 26 = 78 °
