Question

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

Answer 1

let the angles be x,2x and 3x
a q
x+2x+3x=180
6x=180
x=180/6=30
thus the angles are
30 degree
60 degree
and
90 degree
hope this helps

Answer 2

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

Using angle sum property of triangle

1x+2x+3x=180

6x=180

x=180÷6

x=30

1x=1×30=30°

2x=2×30=60°

3x=3×30=90°
