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

but your answer is wrong
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°
the correct answer is; 30+60+90=180
the first angle is 30, another is 60 and the third is 90
