We use quadratic formula then
For a expression
The quadratic formula is
If underroot values becomes negative we use iota(i)
which has value=√-1
The <em>correct answer</em> is:
A∪B={}
Explanation:
Since A∩B = ∅, we know that A and B have no elements in common. This means they are disjoint.
Since the universal set is made up of A and B, and A and B have no elements in common, then A is equal to the complement of B, or A = B'.
Since A and B have no elements in common, A is not a subset of B.
Since we are told at the beginning that A and B are not the empty set, there is no way that their union would be empty. The union of A and B, or A∪B, would contain at least two distinct elements, one from A and one from B.
Vertical angles equal eachother
set angle 4 and angle 8 equal to eachother
3x=x+40
-x both sides
2x=40
÷2 both sides
x=20
solve for angle 4
3 (20)
