In triangle \(ABC\) we have \(\angle B = 60^{\circ}\), side \(AB = 8\) cm and side \(BC = 6\) cm. (i) Find the length of side \(AC\). (ii) Determine \(\sin A\).

Correct Answer A. AC = 2\sqrt{13} cm; \sin A = \frac{3\sqrt{39}}{26}

B. AC = 2\sqrt{7} cm; \sin A = \frac{3\sqrt{39}}{26}

C. AC = 4\sqrt{5} cm; \sin A = \frac{3\sqrt{13}}{26}

D. AC = 2\sqrt{13} cm; \sin A = \frac{\sqrt{39}}{26}

Correct Answer

Correct Option:

AC = 2\sqrt{13} cm; \sin A = \frac{3\sqrt{39}}{26}
