Question

find the trig ratio.
right triangle with hypotenuse 17, adjacent side to ( \theta ) is 15, opposite side is 8, right angle at the bottom right, angle ( \theta ) at the bottom left
( cos \theta = \frac{?}{?} )

Explanation:

Step1: Recall cosine definition

In a right triangle, $\cos\theta = \frac{\text{adjacent}}{\text{hypotenuse}}$.

Step2: Identify sides

Adjacent to $\theta$ is 15, hypotenuse is 17.

Step3: Compute cosine

$\cos\theta = \frac{15}{17}$.

Answer:

$\frac{15}{17}$
