In the right-angled triangle, the hypotenuse is equal to 5.
Referring to θ, the opposite side is equal to 4, and the adjacent side is equal to 3.
sin(θ) = opposite side / hypotenuse = 4/5
cos(θ) = adjacent side / hypotenuse = 3/5
tan(θ) = opposite side / adjacent side = 4/3

and the definitions of sin, cos, tan
that is all you need

sin = opposite/hypotenuse
cos = adjacent/hypotenuse
tan = opposite/adjacent
sin = opposite/hypotenuse
cos = adjacent/hypotenuse
tan = opposite/adjacent
