If n(A)= 8, n(B)= 6, n(AnB)= 5 and n(A')= 4, find n(B') and n(A'nB')​

i do not know the answer

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
