Question

the angles of a triangle are 2 is to 3 is to 4 find each angle

Answer 1

Let the first angle be 2a
Second angle = 3a
Third angle = 4a

2a+3a+4a = 180
=> 9a = 180
=> a = 20

First angle = 40°
Second angle = 60°
Third angle = 80°

Answer 2

angle one : 40°
angle two : 60°
angle three : 80°
