1) 5/13
2) 12/13
3) 12/5
4) 13/12

Answer:

[tex]cos(N)=\frac{5}{13}[/tex]

Step-by-step explanation:

we know that

In the right triangle MNP

[tex]cos(N)=\frac{NP}{MN}[/tex] ----> by CAH (adjacent side divided by the hypotenuse)

substitute the given values

[tex]cos(N)=\frac{10}{26}[/tex]

simplify

[tex]cos(N)=\frac{5}{13}[/tex]
