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 unit
What 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
