Question

find the measure of cd. 101° 13.2 cm 13.2 cm mcd = ?°

Explanation:

Step1: Recall circle - arc property

In a circle, if two chords are equal, then their corresponding minor arcs are equal. Chords $AB$ and $CD$ have the same length ($13.2$ cm). So, arc $AB$ and arc $CD$ are equal in measure.

Step2: Identify arc measure

The measure of arc $AB$ is $101^{\circ}$. Since arc $AB$ and arc $CD$ are equal, the measure of arc $CD$ is also $101^{\circ}$.

Answer:

$101$
