Question

=In AABC, the measure of ZC=90°, CB = 35, AC = 12, and BArepresents the cosine of ZA?37. What ratio

Answer 1

ANSWER:

$\frac{12}{37}$

STEP-BY-STEP EXPLANATION:

The first thing is to draw the triangle ABC:

We have that the trigonometric cosine ratio is given as follows

$\begin{gathered} \cos \theta=\frac{\text{adjacent}}{\text{hypotenuse}} \\ \text{For A, we have} \\ \text{adjacent = 12} \\ \text{hypotenuse = }37 \\ \text{replacing:} \\ \cos A=\frac{12}{37} \end{gathered}$
