Help please!! I am so confused any help is appreciated

Answer:
see explanation
Step-by-step explanation:
(11)
cos L = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{LN}{LM}[/tex] = [tex]\frac{8}{17}[/tex]
(12)
tan M = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{LN}{MN}[/tex] = [tex]\frac{8}{15}[/tex]
(13)
sin M = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{LN}{LM}[/tex] = [tex]\frac{8}{17}[/tex]
