ABC is a right angled triangle of which A is the right angle, BD is drawn perpendicular to BC meets CA produced in D. If AB = 12, AC = 16, BC = 20, then BD =

A

15

B

25

C

10

D

225

Text Solution

Verified by Experts

The correct Answer is:
A

In `Delta BAD, BD = 12 sec theta`
`therefore` From `Delta BAC, sec theta = 5//4`
`therefore BD =12xx(5//4)=15`
