A wind turbine has a tubular steel tower that is 70 meters high. It has three 20-meter long blades attached to the top of the tower, as in the figure below.

(a). Blade 1 starts at the 3 o'clock position and rotates counterclockwise. Find a formula for the height h, in meters, of the tip of blade 1 as a function of the angle ??. As usual, we measure ? counterclockwise from the 3 o'clock position.

(b). Two ladybugs land on the blade, the first on the tip and the second half way between the tip and the rotor. Find functions, h1(?) for the first bug and h2(?) for the second bug, describing the height of each bug above the ground as a function of the angle ?.
