2 Force Members and Trusses! HELP!

**1. The problem statement, all variables and given/known data**

See Figure

**2. Relevant equations**

$\displaystyle \sum F_{x} = 0 $

$\displaystyle \sum F_{y} = 0 $

$\displaystyle \sum M = 0 $

**3. The attempt at a solution**

See Figure

I'm fairly certain the force I drew at point D isn't at a 90 degree angle, but if its not I can't find the perpendicular distance for the horizontal/vertical distances at the point D.

This has been giving me a really big headache and alot of stress lately so some help would be greatly appreciated!
