In right triangle ABC, altitude CD with length h is drawn to its hypotenuse. We also know AD = 12 and DB=3. What is the length of h?
Only sides/angles known are
Base= 12+3,
Angle= Right angle/90°.
No clue how to solve this. I tried many methods. everyone who’s asked this question on here did not get a good answer. Please explain how it is done and what theorem is used.
