Which length are you looking for?

im looking for CD or DC

mathstudent55 · Answer

There are two parts to the theorem. One of them covers this situation.
In a right triangle, if the the altitude to the hypotenuse is drawn, then the length of the altitude is the geometric the lengths of the segments of the hypotenuse.
In this case, 
DC/37 = 37/53
Cross multiply and solve for DC.
