Question

angles of a triangle are in the ratio 1 ratio 2 ratio 1 find all the angle of a triangle classify the triangle into different ways

Answer 1

let the angled =x
ratio =X, 2x, x
sum of all angles =180
x+2x+x=180
4x=180
x=180/4
x=45
first angel =x=45
second angel =2x=2*45=90
third angel =x=45

Answer 2

The sum of all angles of a triangle is 180degree
let the angles be 1x,2x,1x
1x+2x+1x=180
4x=180
x=180/4
x=45 degree
1x=1 x 45
45
2x=2 x 45
90
1x=1 x 45
45
