Please help me! In right triangle ABC the hypotenuse AB is 25 units long and leg AC is 7 units long. Point D lies on side AB so that AD = 10 units. What is the area of triangle ACD?

OpenStudy (cathyangs):

I get that side BC is 24, but where do I go from there?

OpenStudy (cathyangs):

yes... Do I use ratios...like 25/10=24/x?

OpenStudy (anonymous):
