Phil, melissa, noah, and olivia saw a tall tree that cast a shadow 34 feet long. they observed at the same time that a 5-foot-tall person cast a shadow that was 8.5 feet long. how tall is the tree?

  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.
