Question

In the triangle below, what ratio is cos θ?

Answer 1

5:13 since cos is adjacent over the hypotenuse.

Answer 2

`cos(theta)=(5)/(13)`

Ratio is 5:13

Explanation:

We are given with right angle triangle with side lengths

cos theta ratio is adjacent side divide by hypotenuse

In the triangle , adjacent side for theta is 5 and hypotenuse is 13

`cos(theta)=(adjacent)/(hypotenuse)`

`cos(theta)=(5)/(13)`
