Question

the angles of a triangle are in the ratio 1:2:3.find the angles.

Answer 1

let the angles be x , 2x , 3x respectively
we know , that sum of all angles of triangle is 180°

so , here ,

x+2x+3x = 180°

=> 6x = 180°
=> x = 180°/6 => 30°

if x = 30°
then , 2x = 2(30°) = 60°
and 3x = 3(30°) = 90°

therefore , angles of a triangle are 30°,60°,90°


hope this helps

Answer 2

let angles are 1x,2x,3x
so,1x+2x+3x=180
6x=180
x=180/6=30
then angles are
1×30=30
2×30=60
3×30=90
