Question

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

Explanation:

Step1: Recall cosine ratio definition

In a right - triangle, for an acute angle $\theta$, $\cos(\theta)=\frac{\text{adjacent}}{\text{hypotenuse}}$.

Step2: Identify adjacent and hypotenuse for angle $M$

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

Answer:

$\frac{MN}{MO}$
