X = 0 y =-1 because you have to have to find numbers to replace x & y.
The Undefined term that is used to define an angle is a point.
<h2>Further Explanation: </h2><h3>Angle</h3>
- An angle is defined as the union of two rays with a common endpoint.
- The common end point is known as the vertex of the angle while the rays are known as the sides of the angle.
<h3>A ray </h3>
It is a part of a line with one end point and proceeds on in one direction.
<h3>Naming of angles</h3>
- Angles can be named in three different ways;
- Using three Capital letters such as ∠ PQR, or ∠BCD. The middle letter represents the vertex of the angle. Therefore, the angles above are read as "angle PQR" and angle BCD.
- Using the Vertex of the angle. For example, in the case of ∠PQR, can also be called angle Q, while ∠BCD can be called angle C.
- Angles can also be named by placing any number or symbol at the vertex in the interior of the angle. Such that angles can be called angle 1 or angle 3 , or angle 5, and so on.
- Angles are measured using a tool known as a protractor
<h3>Measuring of an angle using a protractor</h3>
- To measure the angle, the mid-point of a protractor is placed on the vertex of the angle.
- Then lining up one side of the angle with the zero line of the protractor.
- Then read the degrees where the other side crosses the number scale.

I'm not quite sure what your asking. Do you want us to subtract 15 - 4? That would be 11.
The sum is 15.
Divide 15 by three to get Jane's age= 5
The remainder, which is J * 2, or ten, is Randy's age.
Randy is ten.
Ummm...... i would say B, i hope that helped! if not, forgive me :)
