Question

What is the length of line segment ED?

Answer 1

a triangle adds up to be 90 always

Answer 2

unless this is paperhangers a^2+b^2=c^2

Answer 3

Is DF a diameter? Are we to assume that?

Answer 4

If it is, that would mean that FED is a right angle.

Answer 5

hmmm doesn't have to be, even if DF is the diameter

Answer 6

so a^2+65^2=60^2

Answer 7

IF FED is a right angle, then FD is also the hypotenuse. Then you could use a^2 + b^2 = c^2 or 65^2 = 60^2 + x^2...or 4225 = 3600 + x^2...4225 - 3600 = c^2...c^2 = 625...c = 25. Then that would be the length of ED.

Answer 8

that was correct thank you so much!

Answer 9

You're welcome!
