b. How much taller is the tree than Frank?
​

Answer 1

Answer:

a. The tree is 30 feet tall.

b. The tree is 24 feet taller than Frank.

Step-by-step explanation:

Since the shadow of the tree is 20 feet and the shadow of Frank is 4 feet, 20+4 is 24.  24+6 is 30, so the tree is 30 feet tall and the tree is 24 feet taller than Frank.
