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
should be accurate to 2 decimal places.

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?

- The difference in length of a spring on a pogo stick from its non-compressed length when a teenager is jumping on it after θ seconds can be described by the function f(θ) = 2sinθ + √2.Part A: Determine all values where the pogo stick's spring will be equal to its non-compressed length. Part B: If the angle was doubled, that is θ became 2θ, what are the solutions in the interval [0, 2π)? How do these compare to the original function?Part C: A toddler is jumping on another pogo stick whose length of its spring can be represented by the function g(θ) = 1 cos^2θ + √2. At what times are the springs from the original pogo stick and the toddler's pogo stick lengths equal?arrow_forwardStudents were asked to prove the identity (sec x)(csc x) = cot x + tan x.
