Doing basic trig like this, itâs helpful to first sketch a right triangle and label the sides with whatever info is given to you. Here youâd put 4 on one side and 5 on the hypotenuse, and a quick glance will recognize that youâve got a 3-4-5 right triangle
Iâm still trying to figure out what ânâ has to do with anything in your question, though. Your first âgivenâ seems totally irrelevant to the rest (sort of like the whole answer âAquamanâ providedâŠ)

sin x = 3/5
tan x = 3/4
cot x = 4/3
I believe you have a triangle with sides 3,4 and 5
3^2 + 4^2 = 25 and 5^2 = 25
