Question

question find the value of cos o rounded to the nearest hundredth, if necessary.

Explanation:

Step1: Recall cosine - ratio formula

In a right - triangle, $\cos\theta=\frac{\text{adjacent}}{\text{hypotenuse}}$. For angle $O$, the adjacent side to angle $O$ is $ON = 6$ and the hypotenuse is $OM=10$.

Step2: Calculate $\cos O$

$\cos O=\frac{ON}{OM}=\frac{6}{10} = 0.60$

Answer:

$0.60$
