2x+x+3x=180

6x=180

x=30 degree

2x=2*30=60 degree

3x=90 degree

when an angle of triangle becomes 90 degree it becomes right angle triangle.

let the angles of a triangle be 2x, x,3x

so 2x+x+3x=180

6x=180

x=180/6=30x=30

2x=60

3x=90

since in a triangle one angle is 90 it is a right angle triangle
