Radio direction finders are set up at points A and B, 8.68 mi apart on an east-west line. From A It is found that the bearing of a signal from a transmitter is N54.3 degrees E,

Question

(Cont.) while from B it is N 35.7 degrees W. Find the distance of the transmitter from B, to nearest hundredth of a mile

Answer 1

Answer 2

Draw and label a diagram!!

Label the transmitter T

∠A = 35.7º

∠B = 54.3º

∠T = 90º

Your choice:

sin A = BT / 8.68

cos B = BT / 8.68
