If in `DeltaABC,a=12cm, b=12cm` and `c=5cm` then distance from a to side BC is

A

`144//13`

B

`65//12`

C

`60//13`

D

`25//13`

Text Solution

Verified by Experts

The correct Answer is:
C
`:'a^(2)=b^(2)+c^(2)`
`:.A=90^(@)`
`:.Delta=1/2bc=1/2(12)(5)=30`
`:.d (A,BC)=(2("area"))/(("base"))`
`=(2(30))/a=60/13`
