Using the cosine ratio formula, the length of RQ to the nearest tenth is: 13.2.
<h3>What is the Cosine Ratio Formula?</h3>The cosine ratio formula is given as, cos ∅ = length of adjacent side / length of hypotenuse.
Find m∠PRT in ΔPRT using the cosine ratio formula:
cos(m∠PRT) = 15/17
m∠PRT = cos^(-1)(15/17)
m∠PRT ≈ 28.07°
Find RQ in ΔPRQ using the cosine ratio formula:
cos(28.07) = RQ/15
RQ = cos(28.07) × 15
RQ ≈ 13.2
