Question

the angle of a triangle are the ratio 3 :1:2 find the measure of each and then

Answer 1

let the angles be 3x, 1x and 2x
3x+1x+2x = 180 (angle sum property)
6x=180°
x=180°/6
x=30°
3x = 3*30=90°
1x= 1*30=30°
2x=2*30=60°

Answer 2

Sum of all angels of triangle =180
let the angle be X
3:1:2
3x+x+2x = 180
6x = 180
x = 180/6
X = 30
3x = 3*30=90
2x = 2*30=60

hope its help you.
