Mrs.T boards plane A and her class boards plane B. The two airplanes leave the airport at the same time. Mrs. T's plane is flying at a heading of 120 degrees and the class plane is traveling at 320 degrees.  If the planes travel at the rates of 700 and 600 miles per hour, respectively, how far apart are they after an hour? If possible use law of sines or law of cosines
