Question

Identify cosA as a fraction and as a decimal rounded to the nearest hundredth.

Answer 1

Answer: B

Step-by-step 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:

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