richigupta: here is your answer.
We know that A+B+C = 180 (Linear Pair)
According to question,
∠A-∠B = 15°
∠B-∠C = 30°
∠A = 15°+∠B
∠C = -30+∠B
(15°+∠B) + (∠B) + (-30°+∠B) = 180°
-15+3∠B = 180°
3B = 195
B = 65
A- (65) = 15
A = 15 + 65
A° = 80
A° = 80 B° = 65
B-C= 30
C = -30 + B
C = -30 + 65
C°= 35
To check,
A° + B° + C° = 180°
80° + 65° + 35° = 180°
Hope it helped.
