# Homework Help: Trig Star question

1. The problem statement, all variables and given/known data
Problem 4:
http://www.nspsmo.org/_data/global/images/2010-11%20Sample%20Problems.pdf [Broken]

2. Relevant equations
Second to last page in same document.

3. 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!
do you know the coordinates of D and E ?

if so, then use pythagoras

But I don't know the coordinates :(

Edit: Hey tiny-tim!!

### tiny-tim

for E, you know the y coordinate of E, and you know the length AE,

so the x coordinate is … ?

Thanks for the help :)
