  42.9 ft

Step-by-step explanation:

The relevant trig relation is ...

  Tan = Opposite/Adjacent

where Opposite in this case is the height of the tree, and Adjacent is the distance to the tree.

  tan(47°) = height/(40 ft)

  height = (40 ft)·tan(47°) . . . . . multiply both sides by (40 ft)

  height ≈ 42.9 ft

The tree is about 42.9 feet tall.
