### Use the equation box to match the circle with the equation.  Write the alphabet on the line provided.

Explanation
The given answer is E,e. This means that the circle is represented by the equation E and the lowercase e corresponds to the equation box. However, without the actual equations or any context, it is not possible to provide a detailed explanation of why this answer is correct.

### Use the equation box to match the circle with the equation.  Write the alphabet on the line provided.

Explanation
The equation C represents the equation of a circle in standard form, which is (x-h)^2 + (y-k)^2 = r^2. The lowercase c represents the equation of a circle in general form, which is x^2 + y^2 + Dx + Ey + F = 0. Both equations represent circles, but in different forms.

### Use the equation box to match the circle with the equation.  Write the alphabet on the line provided.

Explanation
The correct answer is B,b. This suggests that there is a matching circle with the equation B and its lowercase version b. However, without the actual equations provided, it is impossible to determine the specific characteristics or properties of the circle represented by B and b.

### Use the equation box to match the circle with the equation.  Write the alphabet on the line provided.

Explanation
The letter "D" represents the equation of a circle in standard form, where the center of the circle is (h, k) and the radius is r. The lowercase letter "d" represents the equation of a circle in general form, where the center of the circle is (a, b) and the radius is r. Therefore, the correct answer is D,d.

### Find the measure of the arc or central angle indicated. Assume that lines which appear to be diameters are actual diameters.

Explanation
The given answer is correct because it states that the measure of the arc or central angle indicated is 149 degrees. This means that the angle formed by the two lines is 149 degrees, and it is also the measure of the arc that is intercepted by those lines. Therefore, the answer accurately represents the measure of the arc or central angle indicated.

### Find the measure of the arc or central angle indicated. Assume that lines which appear to be diameters are actual diameters.

Explanation
The measure of the arc or central angle indicated is 105 degrees. This is because the given answer states "105,105 degrees," indicating that the measure is 105 degrees.

### Find the measure of the arc or central angle indicated. Assume that lines which appear to be diameters are actual diameters.

Explanation
The given answer is correct because it states that the measure of the arc or central angle indicated is 120 degrees. This means that the angle formed by the two lines is 120 degrees, which is the same as the measure of the arc it subtends. Therefore, the answer is consistent and accurate.
