A flagpole at a right angle to the horizontal is located on a slope that makes an angle of 11° with the horizontal. The flagpole's shadow is 16 meters long and points directly up the slope. The angle of elevation from the tip of the shadow to the sun is 22°. (a) Draw a diagram that represents the problem. Show the known quantities on the diagram and let h indicate the height of the flagpole. (b) Write an equation that you can use to find the height of the flagpole h. h / sin( _ °) = 16 / sin( _ °) (c) Find the height of the flagpole (in m). (Round your answer to one decimal place) _ m

Verify the identity by converting the left side into sines and cosines. (Simplify at each step.) frac{cot^{2}(t)}{7 csc(t)} = frac{1 - sin^{2}(t)}{7 sin(t)} frac{cot^{2}(t)}{7 csc(t)} = frac{cos^{2}(t) / (square)}{7 / sin(t)} = frac{cos^{2}(t)}{square} = frac{1 - sin^{2}(t)}{7 sin(t)}
