What is the length of line segment ED?

OpenStudy (imstuck):

If FD is the diameter as I am thinking it must be, then EF is a right angle, and that triangle is a right triangle. Like this:

OpenStudy (imstuck):

|dw:1405288548337:dw|and use Pythagorean's Theorem to find the length of DE. Do you know how?

OpenStudy (anonymous):

a^2 + b^2 = c^2?

OpenStudy (anonymous):

so ED would be 25?

OpenStudy (imstuck):

Let me check my own work!

OpenStudy (imstuck):

Yep...25 it is! Good!
