If there is any soul out there who is willing to solve a little math problem for fun, give this a shot. :D

Solve triangle DAK:

D=30*
A=45*
K=?

d=20
a=?
k=?

Hows about it? This one is easy enough.

In trig problems it's quite common to denote the angles with capitals and the lengths
of the opposite sides with small letters. :)

Well, the problem is basic trig... Sin rule will do...
Angles add up to 180
