Answer 2

Find BD

Remember soh-cah-toa?

opposite/adjacent

tan30=400/x

xtan30=400

x = 400/tan30

Find BC

Still toa. . . still toa

90 + 60 = 150

180-150 = 30

BAC = 30

tan30=x/400

400tan30=x

BD-BC=CD

If you followed my steps, your answer should come to you.

If you didn't and are a lazy pr*ck who relies on others to do their semester exam problems for them, the answer is A.  Or 461.
