Answer»

solution:-Let 1x,3x,5x1x+3x+5x=1809x=180x=180/9x=20:1x=1×20=20:3x=3×20=60:5x=5×20=100This is the correct answer hai

let 1x, 3x , 5x x+3x+5x=180; 9x=180; x=180/9=20; 1x=1×20=20; 3x20=60; 5x20=100

Let the angles be x,3x,5x

We know that,Sum of all angles of triangle = 180x+3x+5x= 1809x = 180x = 203x = 3×20=605x = 5×20 = 100

let ratio be x1x+2x+3x=1806x=180x=30
