Question

find the value of cos p rounded to the nearest hundredth necessary.

Explanation:

Step1: Recall the cosine definition

In a right - triangle, $\cos\theta=\frac{\text{adjacent}}{\text{hypotenuse}}$. For angle $P$, the adjacent side to angle $P$ is $QP = 15$, and the hypotenuse is $RP=28$.

Step2: Calculate $\cos P$

Using the formula $\cos P=\frac{QP}{RP}$, substitute $QP = 15$ and $RP = 28$. So, $\cos P=\frac{15}{28}\approx0.54$

Answer:

$0.54$
