First, in order to find the length of side w, you must first find the angle W. A triangle must be 180 degrees in total. 93 + 37 makes the triangle only have 130 at the moment. 180 - 130 = 50 So angle W is 50 degrees Now using this, we can use law of sines. Now multiply sin 50 on both sides. It can be written like so: Now plug this in a calculator. Answer is 39.5
