At a point on the ground 50 feet from the foot of a tree, the angle of elevation to the top of the tree is 53°. Find the height of the tree to the nearest foot.
I got 50xtan53 = 66.35 nearest foot ? would I use tan or sin since I'm finding the foot of the tree

tan 53 = height/distance
yes, 66 to nearest foot
The right angle is at the foot of the tree.
ALWAYS draw a picture
tan 53 = opposite (tree) / adjacent(along ground
the hypotenuse is along your line of sight, not used here

correct
in reference to your angle you are involving the opposite and the adjacent side
since tanØ = opposite/adjacent
your choice of tangent was correct.
