In triangle PQR, r= 60inches, <Q=104° and <R=43°. Find the length of a to the nearest inch

Answer 1

I'll give you a choice of lengths p and q, then if you know whether "a" is opposite angle P or Q, you can sort it out. Angle P = 180 - 147 = 33°. Law of sines, upside down: p/sin 33° = 60/sin 43° and p = 48 in. q/sin 104° = 60/sin 43° which yields q = 85 in.
