Team A is located on the south bank of a river. Teams B and C are located on the north bank. The angle formed from Team C to Team A is S 42o W. Team C is 10 feet due east of Team B and 12 feet from Team A. How far is Team A from Team B?
a. 9.1 ft
b. 8.1 ft
c. 12.4 ft
d. 20.6 ft
I got 8.1 every time I calculated it, but the answer is 9.1. How would you solve this?
