Let the angles be 1x,2x and 3x sum of angles in a triangle = 180 1x+2x+3x = 180 6x = 180 x = 30 the angles are 30,60,90 degrees respectively.

Let the three angles according to ratio be x,2x and 3x Sum of angles of triangle=180 degrees According to Problem x+2x+3x=180 =>6x=180=>x=180/6=30 therefore, 1st angle=30 degree 2nd angle=2*30=60 degree 3rd angle=3*30=90 degree To verify=(30+60+90)degree=180 degree[VERIFIED]

sum of angles in a triangle = 180

1x+2x+3x = 180

6x = 180

x = 30
