A communications tower is located at the top
of a steep hill, as shown. The angle of
inclination of the hill is 77°. A guy wire is to be
attached to the top of the tower and to the
ground, 102 ft downhill from the base of the
tower. The angle formed by the guy wire is 9°.
Find the length of the cable required for the
guy wire.
9°
102 ft
77°
NOTE: The picture is NOT drawn to scale.
length of guy-wire =
ft
Enter your answer as a number; your answer

Aloha Airlines Flight 007 is flying due east but finds it necessary to detour around a group of
thundershowers. The plane 1st turns at a bearing of N 73° E, flies for a while, then 2nd turns to intercept
the original path and travels for 50 km at a bearing of S 41° E, back to the original path.
As stated the plane traveled 50 km in the 2nd leg of the journey getting back to the path. How far did the
plane travel in the 1st leg of the journey?
