If the matrix `A=[[8,-6,2],[-6,7,-4],[2,-4,lambda]]` is singular then `lambda` is

If the matrix A=[(8,-6,2),(-6,7,-4),(2,-4,lamda)] is singular one, then lamda is

I: If the matrix A =[(8,-6,2),(-6,7,-4),(2,-4,lamda)] is singular one, then lamda=3 II: If the matrix [(cos theta, sin theta, 0),(sin theta, cos theta, 0),(0,0,1)] is singular then theta=pi//2

If the matrix [[0,1,-2],[-1,0,3],[lambda,-3,0]] is singular,then lambda=

Select and write the correct answer from the given alternatives in each of the following:The matrix [[lambda,7,-2],[4,1,3],[2,-1,2]] is a singular matrix if lambda is (degenerate matrix)

Assertion (A) : If the matrix A=[{:(1,3,lambda+2),(2,4,8),(3,5,10):}] is singular , then lambda=4 . Reason (R ) : If A is a singular matrix, then |A|=0

If the rank of A=[[1,2,3,4],[2,4,6,8],[3,6 ,lambda, mu]] is 1 then lambda+mu

If the matrix [(1,2,-1),(-3,4,k),(-4,2,6)] is singular, then the value of k is equal to
