A hot-air balloon is flying over a dry lake when the wind stops
blowing. The balloon comes to a stop 450 feet above the ground at point D
as shown in Figure 9. A jeep following the balloon runs out of gas at point A.
The nearest service station is due north of the jeep at point B. The bearing of
the balloon from the jeep at A is N 13 degree E, while the bearing of the balloon from
the service station at B is S 19 degree E. If the
is 128, how far will the people in the jeep have to walk to reach the ser vice station
at point B?
