In triangle $PQR$, $PQ = 8$ cm and $QR = 7$ cm. Calculate \(\frac{\sin \angle PRQ}{\sin \angle

Question

In triangle $PQR$, $PQ = 8$ cm and $QR = 7$ cm. Calculate $\frac{\sin \angle PRQ}{\sin \angle QPR}$. Hence, if $\angle QPR = 55{}^\circ$ and $\angle PRQ$ is acute, find $\angle PQR$.

Accepted Answer

(i) $\frac{8}{7}$ (ii) $55.6^\circ$
