Given right triangle ABCABC with altitude \overline{BD}BD drawn to hypotenuse \overline{AC}AC. If AD=4AD=4 and BD=2,BD=2, what is the length of \overline{DC}?DC?
Given right triangle(ABC) with right angle(ABC) and altitude(BD).
Since AD = 4 and BD = 2, use the formula: AD/BD = BD/DC
---> 4/2 = 2/DC
and finish.
