THANK YOU SO SO MUCH OMG during my right triangle unit i literally skipped the last question which was the bearing problem and i got a really bad grade....tomorrow is my test in second period and i'm hoping to do way better 💗😞 you made the problems seem so much easier tysm

length from A = ( 1 / 2 ) * 3.46^2 * sin ( 42.3 ) * sin ( 32.5 ) / sin ( 105.2 ) / [ ( 1 / 2 ) * ( 3.46 ) * sin ( 42.3 ) ]

I never liked bearing questions in school
