Triangle ABC is a right triangle with angle ABC equal to 90 degrees. The length of AC is 7 units and the length of AB is 5 unitWhat is the length, in units, of segment CD?
Angle ACB =Angle ADC
Angle ABC = Angle CAD
So.....Triangle CBA is similar to triangle DAC
So
DC / AC = CA / BA
DC / 7 = 7 / 5
DC = 7* 7 /5 = 49 / 5
