Question

in circle r with ( mangle qrs = 150^{circ} ), find the measure of minor arc ( overarc{qs} ).

Explanation:

Step1: Recall the central angle - arc relationship

The measure of a minor arc is equal to the measure of its central angle.

Step2: Identify the central angle

Here, the central angle for arc $\overset{\frown}{QS}$ is $\angle QRS$. Given that $m\angle QRS = 150^{\circ}$.

Answer:

$150^{\circ}$
