Just remember this mnemonic:   Soh Cah Toa

Sin Θ = opposite/hypotenuse

Cos Θ = adjacent / hypotenuse

Tan Θ = opposite / adjacent 

So in your triangle:
Cos M = n/p   ⇒  n is the adjacent side; p is the hypotenuse

Cos N = 8/p   ⇒ 8 is the adjacent side; p is the hypotenuse 

Tan M = 8/n   ⇒ n is the adjacent side; 8 is the opposite side

Tan N = n/8   ⇒ 8 is the adjacent side; n is the opposite side
