Calculate side from angles and some other sides in triangle

Hello,

I would like the forumla for calculating the length of B.

What is known is the length of A (the entire length of that side), A2, D, D2 the angle of r and r2 (90 degrees).

What is the formula for calculating the length of B?

Thanks in advance!

Regards,
Niklas

B = AD/A2 (since B/A = D/A2).
