Given right triangle ABC with altitude BD drawn to hypotenuse AC. If AD=4 and DC=8, what is the length of BD? (Note: the figure is not drawn to scale.)
Given a right triangle ABC with altitude BD drawn to hypotenuse AC. If AD=4 and DC=8, what is the length of BD?
BD/4 = 8/BD
BD = sqrt(4 * 8)
BD = 2√8
