Question

question find the value of cos u rounded to the nearest hundredth, if necessary.

Explanation:

Step1: Recall cosine definition

In a right triangle, $\cos\theta = \frac{\text{adjacent}}{\text{hypotenuse}}$ for an angle $\theta$.
For $\angle U$, adjacent side to $U$ is $VU = 40$, hypotenuse is $WU = 41$.

Step2: Calculate $\cos U$

$\cos U = \frac{VU}{WU} = \frac{40}{41}$

Step3: Compute and round

$\frac{40}{41} \approx 0.98$ (rounded to nearest hundredth)

Answer:

0.98
