Answer:
3x° + 2x+60° + 5x-40° = 180° (Angle Sum Property)
or, 10x + 20° = 180°
or, 10x = 180-20 = 160°
or, x = 160/10 = 16°.
3x = 3(16) = 48°
2x + 60 = 2(16) + 60° = 92°
5x - 40 = 5(16) - 40 = 40°

Answer:
Let the angles be 3x, (2x+60) and (5x-40)
Acc to question. 3x + 2x+60 + 5x-40 =180
=>10x + 20 = 180
=>10x = 180 - 20
=>10x = 160
=>x = 160/10
=>x = 16
Therefore, 3x = 3 × 16 = 48°
2x + 60 = 2 × 16 + 60 = 92°
5x - 40 = 5 × 16 -40 = 40°
Hope it helps
