Before a parade you are holding one of the tethers attached to the top of a character balloon that will be in the parade. The balloon is upright and the bottom is floating approximately 20 feet above ground level. You are standing approximately 100 feet from the balloon (see figure). 20 ft 6 ft - 100 ft→ Not drawn to scale (a) Find an expression for the length / of the tether in terms of h, the height of the balloon from top to bottom. | = (b) Find an expression for the angle of elevation e from you to the top of the balloon. e = (c) The angle of elevation to the top of the balloon is 20°. Find the height h. (Round your answer to two decimal places.) h = | ft
