Question

A 12ft. pole casts a shadow of 16ft. What is the distance between the end of the shadow and the top of the pole?

A^2 + 12ft^2 = 16^2
A^2 + 144 = 256
A^2 + 0 = 256 - 144
A^2 = 112
A^2 = SQRT of 112 or 10.58ft.

Answer 1

I agree.

Answer 2

144 + 256 = 400

Square root of 400 is 20

My answer makes more sense than yours.

Answer 3

You need to subtract 144 from each side and not add it. So.. I still agree with your answer.
