Question

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

Explanation:

Step1: Recall the cosine formula

In a right - triangle, $\cos\theta=\frac{\text{adjacent}}{\text{hypotenuse}}$.

Step2: Identify the adjacent side and hypotenuse

For angle $O$, the adjacent side is $6$ and the hypotenuse is $10$.

Step3: Calculate $\cos O$

$\cos O=\frac{6}{10}=0.6$

Answer:

$0.6$
