Question : If $\triangle$PQR is right-angled at Q, PQ = 12 cm and $\angle$PRQ = 30°, then what is the value of QR?
Option 1: $12\sqrt{3}$
Option 2: $12\sqrt2$
Option 3: $12$
Option 4: $24$
Correct Answer: $12\sqrt{3}$
Solution : $\triangle$ PQR is a right-angled at Q. So, Hypotenuse is PR. We know, tan $x$ = $\frac{\text{Opposite Side}}{\text{Adjacent Side}}$ tan($\angle$PRQ) = $\frac{PQ}{QR}$ ⇒ tan 30° = $\frac{12}{QR}$ ⇒ $\frac{1}{\sqrt{3}} = \frac{12}{QR}$ $\therefore$ QR = $12\sqrt{3}$ cm Hence, the correct answer is $12\sqrt{3}$.
