Therefore, the difference of arc measures
\( m \overset{\frown}{AC} - m \overset{\frown}{DE} \) is
\( 80^\circ - 24^\circ = 56^\circ \).

To solve this problem, we'll use the fact that the angle formed by two secants intersecting outside of a circle is equal to half the difference of the measures of the arcs that the secants intercept.

Given:

- The measure of angle
\( ABC = 28^\circ \)

- The measure of arc
\( \overset{\frown}{AC} = 80^\circ \)

- The measure of arc
\( \overset{\frown}{DE} = 24^\circ \)

The formula to find the angle formed by two intersecting secants is:


\[ m \angle ABC = (1)/(2) (m \overset{\frown}{AC} - m \overset{\frown}{DE}) \]

Now, we can calculate step by step:

1. Substitute the given values into the formula:


\[ 28 = (1)/(2) (80 - m \overset{\frown}{DE}) \]

2. Double both sides to eliminate the fraction:


\[ 56 = 80 - m \overset{\frown}{DE} \]

3. Solve for
\( m \overset{\frown}{DE} \):


\[ m \overset{\frown}{DE} = 80 - 56 \]


\[ m \overset{\frown}{DE} = 24^\circ \]

Since
\( m \overset{\frown}{DE} \) is already given as
\( 24^\circ \), the calculation confirms that the given values are consistent with the properties of intersecting secants.

Therefore, the difference of arc measures
\( m \overset{\frown}{AC} - m \overset{\frown}{DE} \) is
\( 80^\circ - 24^\circ = 56^\circ \).
