A flagpole at a right angle to the horizontal is located on a slope that makes an angle of 15° with the horizontal. The flagpole casts a 16-meter shadow up the slope when the angle of elevation from the tip of the shadow to the sun is 20°. (a) Draw a triangle to represent the situation. Show the known quantities on the triangle and use the variable h to indicate the height of the flagpole. (b) Write an equation involving the unknown quantity h.
