If determinant of A = 5 and A is a square matrix of order 3 then find the determinant of adj(A)

Text Solution

Verified by Experts

The correct Answer is:
1
Since, angle bisector of a and b
`impliesh(hata+hatb)=h((a)/(|a|)+(b)/(|b|))` . . . (i)
Given, a+b is alongg angle bisector
`implies mu((a)/(|a|)+(b)/(|b|))=a+b`
only, when `|a|=|b|=mu`
`therefore|a|=|b| implies lamda=1`.
