If you search the law of sines on the internet, it'll mostly give you A/sin(a) = B/sin(b) = C/sin(c). But, to find a missing angle, it's best to use sin(a)/A = sin(b)/B = sin(c)/C. Is there a way to use A/sin(a) = B/sin(b) = C/sin(c) …

sin x = x − x 3 /3! + x 5 /5! − x 7 /7! + ..., where x is in radians. For example, to find out sine 23, first convert 23 to radians by dividing it by 180 and then multiplying by π. We get 23/180 π = 0.401425727958696 ≈ …
