Problem

In a right-angled triangle PQR, ∠Q=90∘\angle Q = 90^\circ. Side QR = 8 cm and ∠P=30∘\angle P = 30^\circ. (i) State the names of the sides that are opposite, adjacent, and hypotenuse with respect to ∠P\angle P. (ii) Write the trigonometric ratio that involves side QR and side PQ. (iii) Calculate the length of side PQ, leaving your answer in simplest form if necessary.
