Answer 1

B

Explanation:

adj./ hypo.

cos a = 13/14.5 = 0.9

Answer 2

Answer: B

Explanation:

Cosine is defined as the ratio of the adjacent and the hypotenuse. The adjacent segment to the angle A would be the base of the triangle. The hypotenuse is the longest side of a triangle. Taking their ratio, we get that:

`cos(A)=13/14.5=0.9`
