Answer:
A = 80°
B = 65°
C = 35°
Step-by-step explanation:
A - B = 15° => A = (15 + B)°
B - C =30° => C = (B - 30)°
In a triangle,sum of three angles = 180°
A + B + C = 180°
15 + B + B + B - 30 = 180°
3B - 15 = 180°
3B = 180 + 15
3B = 195°
=> B = 65°
=> A = (15 + B)°
A = 15 + 65
A = 80°
=> C = (B - 30)°
C = 65 - 30
C = 35°
