Question

If angles of a triangle are in ratio 1:2:3 .find value of each angle.what type of triangle is this.

Answer 1

given ratio=1:2:3

let the 3 angles be 1x,2x,3x

sum of angles in a triangle is 180 degrees

1x+2x+3x=180

6x=180

x=180/6

x=30

therefore,the 3 angles are 30 degrees,60 degrees,90 degrees.

the triangles is in the form of right angled triangle.

hope the answer is helpful!!
