In a right triangle abc, cd is an altitude, such that ad=bc. find ac, if ab=3 cm, and cd=√2 cm.

Given that triangle ABC is right angle triangle. CD is altitude such that AD=BC

ABC is a right angle triangle so apply Pythogorean theorem

     (Given that AD = BC)

     (Given that AB=3)

...(i)

ADC is a right angle triangle so apply Pythogorean theorem

...(ii)

Plug value (ii) into (i)

Hence final answer is
