Answer:(iii)

Step-by-step explanation:

then the angles are 3x, 2x, and,x

(i) largest angle= 30° :- x=10°

=> the angles are:- 30°,20° &10°

((which is not possible))

(ii) largest angle=60°:- x=20°

=>the Angles are:-60°,40,&20°

((which is not possible))

(iii) largest angle= 90° :- x=30°

=> the angles are:- 90°,60°&30°

((which is possible)) ✓✓✓

(i) largest angle= 120° :- x=40°

=> the angles are:- 120°,80°, & 40°
