Suppose A and B are 2 sets in a universal set U. The definition subsets is: We say that A is a subset of B (AC B) if and only if: Vx E U, if x E A then x E B Write the negation of the universal conditional statement in the definition: That is write what it means to say that A is not a subset of B (A ¢B):
Angles in Circles
Angles within a circle are feasible to create with the help of different properties of the circle such as radii, tangents, and chords. The radius is the distance from the center of the circle to the circumference of the circle. A tangent is a line made perpendicular to the radius through its endpoint placed on the circle as well as the line drawn at right angles to a tangent across the point of contact when the circle passes through the center of the circle. The chord is a line segment with its endpoints on the circle. A secant line or secant is the infinite extension of the chord.
Arcs in Circles
A circular arc is the arc of a circle formed by two distinct points. It is a section or segment of the circumference of a circle. A straight line passing through the center connecting the two distinct ends of the arc is termed a semi-circular arc.

please help with this proof regarding subsets.
thank you so much!
![**Definition of Subsets**
Suppose \( A \) and \( B \) are two sets in a universal set \( U \). The definition of subsets is as follows:
We say that \( A \) is a subset of \( B \) (\( A \subseteq B \)) if and only if:
\[ \forall x \in U, \text{ if } x \in A \text{ then } x \in B \]
**Negation of the Universal Conditional Statement**
Write the negation of the universal conditional statement in the definition. That is, write what it means to say that \( A \) is not a subset of \( B \) (\( A \nsubseteq B \)):](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F1cfd53d0-8cf3-4e08-8682-e45234c2f04e%2F47f56032-d8c7-4d52-a034-6db1360f2042%2F79sm05g_processed.jpeg&w=3840&q=75)
