Question

Find the measure of the angles of a triangle in each of the following cases first case is The angles are in the ratio two ratio three ratio four please give me the answer

Answer 1

ratios of angles 2:3:4

let one angle=2x

let second angle=3x

let third angle=4x

so,

by angle sum property of triangle

2x+3x+4x=180°

9x=180°

X=180/9

X=20

so

but,

angle one=2x=2(20)=40

second angle=3x=3(20)=60

third angle=4x=4(20)=80
