step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)
