The Attempt at a Solution



I know how to solve everything but the minor chord lengths: CD, DE, EF

The only thing I could think of was to do something similar to problem 3, using C to the bottom left corner and its adjoining leg (and do the same for each chord), but I don't think I can solve the problem that way.

Any help is appreciated!

hi rebat! :smile:

do you know the coordinates of D and E ?

if so, then use pythagoras :wink:​
 
But I don't know the coordinates :(

Edit: Hey tiny-tim!
 
for E, you know the y coordinate of E, and you know the length AE,

so the x coordinate is … ? :smile:​
 
I am disappointed I didn't see that!

Thanks for the help :)
