Answer:
See below.
Step-by-step explanation:
A helpful way to memorize these 3 ratios is by using the mnemonic below.
SOH-CAH-TOA:-
Sine=Opposite/Hypotenuse - Cosine= Adjacent/Hypotenuse - Tangent= Opposite/Adjacent.
So for the given triangle:-
sin X = 4√5/12 = √5/3.
cos x = 8/12 = 2/3.
tan x = 4√5/ 8 = √5/2
