The angles of a triangle A B C are in Ad...

The angles of a triangle `A B C` are in `AdotPdot` and it is being given that `b : c=sqrt(3):sqrt(2)` , find `/_Adot`

Text Solution

Verified by Experts

As angles are in A.P.,
`:. 2/_B = /_A+/_C`
Now, `/_A+/_B+/_C = 180`
`/_B+2/_B = 180`
`/_B = 60^@`
Now, from sine law,
`b/sinB = c/sinC`
`b/c = sinB/sinC`
