Question

find the value of cos l rounded to the nearest hundredth, if necessary. answer attempt 1 out of 2 cos l =

Explanation:

Step1: Recall cosine formula

In a right - triangle, $\cos\theta=\frac{\text{adjacent}}{\text{hypotenuse}}$. For $\angle L$, the adjacent side to $\angle L$ is $LM = 4$ and the hypotenuse is $LN=8$.

Step2: Calculate cos L

$\cos L=\frac{LM}{LN}=\frac{4}{8}=0.5$

Answer:

$0.5$
