$\Delta ABC$ માં,$\angle A = 2x - 10^{\circ}$,$\angle B = x + 10^{\circ}$ અને $\angle C = 2x - 20^{\circ}$ હોય,તો $\Delta ABC$ ના દરેક ખૂણાનું માપ શોધો.

• A
  $\angle A = 70^{\circ}, \angle B = 50^{\circ}, \angle C = 60^{\circ}$
• B
  $\angle A = 60^{\circ}, \angle B = 60^{\circ}, \angle C = 60^{\circ}$
• C
  $\angle A = 80^{\circ}, \angle B = 40^{\circ}, \angle C = 60^{\circ}$
• D
  $\angle A = 75^{\circ}, \angle B = 45^{\circ}, \angle C = 60^{\circ}$
