Question

Find the cosine of ∠U. A) 15 17 B) 17 15 C) 8 15 D) 8 17

Answer 1

Answer:

$cos(A)=\frac{8}{17}$

Step-by-step 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

$cos(A)=\frac{AC}{AB}$ ----> by CAH

substitute the given values

$cos(A)=\frac{8}{17}$
