is this multiple choice or no ?
anonymous
  • anonymous
You cannot, since it is not a right triangle
anonymous
  • anonymous
no its not multiple choice it just asks me What is the length of line segment ED?
anonymous
  • anonymous
its a triangle inside of a circle

if DF is a diameter then it is aright angled triangle.
anonymous
  • anonymous
by the picture it looks like it is the diameter
anonymous
  • anonymous
yeah i think its the diameter

i just have no clue how to solve this thing

as @surjithayer said, that is, Thales' theorem -> http://www.mathopenref.com/thalestheorem.html

so.. since it's a right triangle knock yourself out with the "pyghatorean theorem" :)

|dw:1437179218568:dw| \(\bf \textit{pythagorean theorem}=c^2=a^2+b^2\implies c^2-b^2=a^2\\ \quad \\\implies \sqrt{c^2-b^2}=a \\ \quad \\ \qquad \begin{cases} c=65\\ b=60 \end{cases}\implies \sqrt{65^2-60^2}=a\)

jk wrong thing
anonymous
  • anonymous
63 was wrong for me
anonymous
  • anonymous
do what @jdoe0001 put up
anonymous
  • anonymous
i did and still got it wrong oh well

i must be doing something wrong again like always
anonymous
  • anonymous
i'm just going to submit this quiz
anonymous
  • anonymous
im still kind of curious to know though what was the answer?
anonymous
  • anonymous
\[\sqrt{65^2-60^2}=\sqrt{\left( 65-60 \right)\left( 65+60 \right)}=\sqrt{5*125}=\sqrt{5*5*25}=25\]
