Question

find the measure of the red arc or chord in \\(\odot c\\).
\\(m\overarc{ab} = \square^\circ\\)

Explanation:

Step1: Identify congruent chords/arcs

Chords $AB$ and $ED$ are marked congruent, so their corresponding arcs $\overset{\frown}{AB}$ and $\overset{\frown}{ED}$ are congruent.

Step2: Match arc to central angle

The measure of an arc equals its central angle. The central angle for $\overset{\frown}{ED}$ is $75^\circ$.

Answer:

$75$
