A right triangle ABC is inscribed in a circle with a diameter of 10 cm. An altitude BD is drawn from the vertex B to the hypotenuse AC. If the length of the leg AB is 6 cm, what is the length of the segment AD?
Given :
A right triangle ABC is inscribed in a circle of diameter 10 cm.
So, hypotenuse AC = 10 cm.
AB = 6 cm.
BD is the altitude from B to hypotenuse AC, meeting it at D.
Formula Used :
In a right triangle, the projection of a leg on the hypotenuse:
AD =
Solution :
AD =
=
= 3.6 cm
