Question

Find the cos of angle y

Answer 1

Answer:4/5

Step-by-step explanation:

Answer 2

ANSWER

$\cos(y) = \frac{4}{5}$

EXPLANATION

From the mnemonics SOH-CAH-TOA.

We want to find the cosine of y

CAH means cosine ratio involves adjacent over the hypotenuse.

$\cos(y) = \frac{adjacent}{hypotenuse}$

From the right by triangle, the side ajacent to angle y is 64 units and the hypotenuse is 80 units.

$\cos(y) = \frac{64}{80}$

$\cos(y) = \frac{4}{5}$
