Question

ratio of angle of triangle is 1:2:3 find the angles

Answer 1

let the angle measures is x
we know that by angle sum property ,the sum of all angles is 180°
atq.......................... x+2x+3x=180
                                 6x=180°
                                  x=30°

the first angle is x=30°
the second angle is 2x=2×30=60°
the third angle is 3x=3×30=90°

Answer 2

Let the angles be 1x , 2x , 3x

Therefore, we know that sum of angles of a triangle is 180°

ATQ :
1x + 2x + 3x = 180
6x = 180
x = 180/6
x = 30

Therefore, the angles are :
x = 30°
2x = 60 °
3x = 90°

Hope it help you...
