Question

use soh - cah - toa to find cos(c).

Explanation:

Step1: Recall CAH formula

\(\cos(\theta)=\frac{\text{Adjacent}}{\text{Hypotenuse}}\)

Step2: Identify adjacent and hypotenuse

For \(\cos(C)\), adjacent side is \(14\), hypotenuse is \(30\)
\(\cos(C)=\frac{14}{30}=\frac{7}{15}\approx0.47\)

Answer:

\(0.47\)
