In ΔWXY, the measure of ∠Y=90°, YX = 40, XW = 41, and WY = 9. What ratio represents the cosine of ∠W?

andreyandreev [35.5K]

Answer:

$\cos(W) = \frac{9}{41}$

Step-by-step explanation:

Given

$\angle Y = 90^o$

$YX = 40; XW = 41; WY = 9$

Required

Determine $\cos(W)$

The question is illustrated with the attached image.

So:

$\cos(W) = \frac{Adajacent}{Hypotenuse}$

$\cos(W) = \frac{WY}{XW}$

This gives:

$\cos(W) = \frac{9}{41}$
