B A 17 mi. 25 mi. 60° 36° b C A Assuming red team knows the bearings and distances from checkpoint A and checkpoint C to checkpoint B, they can calculate the distance (b) between checkpoint A and checkpoint C using the Law of Sines. First they need to calculate the angle B in degrees using the Triangle Sum Theorem, then they will set up ratios using angle B and distance b, and one of the other two sides. Finally the team will need to solve it algebraically. Calculate the distance b and round it to one decimal place.​
