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

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

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 "[[1,2,x],[4,-1,7],[2,4,-6]]" in a singular matrix,then "x" is equal to "

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

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
