Answer:

  20 ft

Step-by-step explanation:

The tree's shadow is 34/8.5 = 4 times the length of the person's shadow, so the tree is 4 times a tall as the person:

  4×5 ft = 20 ft . . . . . the height of the tree

_____

Shadow lengths are proportional to the height of the object casting the shadow.
