Black vultures excel at gliding flight; they can move longdistances through the air without flapping their wings whileundergoing only a modest drop in height. A vulture in a typicalglide in still air moves along a path tipped 3.5 degrees below thehorizontal.

If the vulture moves a horizontal distance of 100m, how much height does itlose?
