(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

given this formula, i have to solve for A

n=sin[(A+B)/2]/sin(B/2)

2. Relevant equations

3. The attempt at a solution

Heres how far I got

2nsin(B/2) = sin(A+B) i know this can expand out to

=sinAcosB + cosAsinB but this isnt much help. Anyone got a suggestion
