Answer 1

this answer is D) 8/17

Explanation:

thanks for the answer. I really love this one!

Answer 2

`cos(A)=(8)/(17)`

Explanation:

The correct question is

Find the cosine of ∠A

The picture in the attached figure

we know that

In the right triangle ABC

The cosine of angle A is equal to divide the adjacent side to angle A by the hypotenuse of the right triangle

so

`cos(A)=(AC)/(AB)` ----> by CAH

substitute the given values

`cos(A)=(8)/(17)`
