Question

given right triangle mno, which represents the value of cos(m)?

Explanation:

Step1: Recall cosine formula

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

Step2: Identify sides for $\angle M$

For $\angle M$ in $\triangle MNO$, adjacent side is $MN$ and hypotenuse is $MO$. So $\cos(M)=\frac{MN}{MO}$.

Answer:

$\frac{MN}{MO}$ (the option that reads $\frac{MN}{MO}$)
