for the second, see the diagram below.

i used F for Franklin, C for Centerville, and R for Rosemont

Note that angle FCR = 32 + 90 + 15 = 137 degrees

we want the distance FR

By the cosine rule:

km

you can use the sine rule to find angle CRF, and then finding the bearing is easy from there - November 10th 2007, 10:05 PMJhevon
