Question

a tree casts a 13 foot shadow. the distance from the top of the tree to the far end of the shadow is 22 feet. if the tree is perfectly straight and creates a right angle with the ground, how tall is the tree?

Answer 1

Explanation:

Use the Pythagorean Theorem to find the missing side.

a2 + b2 = c2 (the #2 means squared)

a2 + 13(2) = 22(2)

a2 + 169 = 484

a2 = 484-169

a2 = 315

a = the square root of 315

a = 17.75

**answer: The tree is 17.75 feet high

Answer 2

13+B=22
-13. -13
B=9
Answer is 9
