Triangle XYZ, XY= 80, ZY= 64 XZ= 48 what is the cosine

Answer:

$cos=\frac{4}{5}$

Step-by-step explanation:

Cosine is the adjacent side over the hypotenuse (You can remember sin, cos, and tan by using sohcahtoa or sin = opposite/hypotenuse, cos = adjacent/hypotenuse, tan = opposite over adjacent). I think a picture would help, too.

I attached a picture of what I think the triangle would look like.

If the picture is right (we're assuming it is) and going with what we're given (the triangle was addressed as triangle XYZ, meaning that <u>angle Y is in the middle and that's the one we'll use</u>).

Looking at my picture then:

$cos=\frac{64}{80} \\cos=\frac{8}{10} \\cos=\frac{4}{5}$ .
