What does the sine law relate in a triangle?

📘 Worked solution
The sine law pairs each side with the sine of the angle directly opposite it - a/sin(A)=b/sin(B)=c/sin(C).

And one from the hard end

"Two lookout towers 500m apart spot a wildfire. The angle at Tower A (between the line to Tower B and the line to the fire) is 55°; at Tower B it's 65°. Find the distance from Tower A to the fire."
