Question

the three angles of a triangle are in ratio 1:2:1. Find all the angles of the the triangle​

Answer 1

45,90,45 are the angles of a triangle which are in the ratio of 1:2:1 .
we know that sum of the angles in a triangle is 180 .
x+2x+x=180
4x=180
x=45 .
hope it helps you .

Answer 2

let the angle be 1x,2x and 1x

we know that the sum of angle of triangle is 180

1x+2x+1x=180

4x=180

x= 180/4

x=45

then,

required angles are

1x=1×45=45

2x=2×45=90

1x= 1×45=45
