Help please...............

Step-by-step explanation:

All we have to do here is to find the measure of the central angle; the measure of the central angle of a circle is the same measure as the arc it intercepts. Angle DQE in degrees = arc DE in degrees. Use the arc length formula to find the measure of the central angle:

and filling in:

which simplifies to

which simplifies a bit more to

so

degrees. That means that arc DE also measures 50.04 degrees.
