Question:

Triangulation is used to locate airplanes, boats, or vehicles that transmit radio signals. The distances to the vehicle are found and the directions calculated by measuring the strength of the signal at three fixed receiving locations. Receiver B is 18 km from Receiver A at a bearing of 122°. Receiver C is 26 km from Receiver A at a bearing of 80°. The signal from a source vehicle to Receiver A indicates a distance of 15 km. The distance from the source vehicle to Receiver B is 8 km and to Receiver C is 25 km. What is the bearing from Receiver A to the source vehicle? (You might try making a scale drawing of this situation, and use your compass to get a general idea of the location of the source before starting the calculations.)
