Step-by-step explanation:

smallest angle = 30°

let the difference be d

then other angle are 30°+d and 30°+2d

∵sum of all angles of triangle = 180°

⇒30°+(30°+d) +(30°+2d) = 180°

⇒3d = 180° - 90° = 90

⇒d = 30°

so others angles are 30°+10° = 40° and 30°+ 20° = 50°

hope it helps.... regards

jaaishriraam1: but your answer is wrong

jaaishriraam1: sum of angles in a triangle is 180°. But, in the answer which you have given had the sum of angles as 40°+50°+30°=120°

jaaishriraam1: the correct answer is; 30+60+90=180

jaaishriraam1: the first angle is 30, another is 60 and the third is 90
