For each question: Show all work. Justify each answer in the space provided. Circle final answers.
(1) A TV camera at ground level is filming the lift-off of the space
shuttle at a point 2000 ft from the launch pad.
(1a) Represent this situation by drawing a right ∆. Label the angle of
elevation as θ, the altitude of the shuttle as s, the hypotenuse as h and
the base as 2000 ft.
(1b) Let s = 1000 ft, find θ.
(1c) Let s = 1000 ft, find h.
(1d) Let s = 4000 ft, find θ.
(1e) Let s = 4000 ft, find h.

(2) You are driving toward a mountain range. The angle of
elevation to the peak of the largest mountain is 3.5° After you drive 13
miles closer to the mountain, you find that the angle of elevation is 9°
Find the height of the mountain. Draw and label 2 right ∆s with a
common right angle depicting this scenario.
