You should recognize the 3-4-5 right-angled triangle, so
cosp = 4/5
tan p = sinp/cosp = (3/5) / (4/5) = 3/4
if sinp =3/5 and p is an acute angle find tanP

draw a right triangle with sinP=3/5
That is, opposite/hypotenuse = 3/5
Now surely you recognize a 3-4-5 right triangle, so the adjacent side is 4.
Or, if you want to do the math, it is √(5^2-3^2) = 4
tanP = opposite/adjacent = 3/4
That is, opposite/hypotenuse = 3/5
