Question

Triangle P Q R is shown. Angle Q P R is a right angle. The length of hypotenuse Q R is 14.1 and the length of P R is 12.7.

Answer 1

Answer:

The correct option is option (c).

Sin \ P= \frac {RQ}{PQ}

Step-by-step explanation:

Answer 2

Answer:

∠ R ≈ 26°

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos R = $\frac{adjacent}{hypotenuse}$ = $\frac{PR}{QR}$ = $\frac{12.7}{14.1}$ , thus

R = $cos^{-1}$($\frac{12.7}{14.1}$ ) ≈ 26° ( to the nearest degree )
