Question

In exercises $2-7$ find the measure of the arc.

$\stackrel{⏜}{AB}$

Short answer

(a) The measure of an arc $\stackrel{⏜}{AB}$ is $50.$

Step-by-step solution

Step 1. Given information:

The given figure is,

Step 2. Concept used:

Following properties are used here,

The arc length of a circle can be calculated with the radius and central angle.

Step 3. Applying the concept:

Here, in the figure

$\angle AOB=50°$

Since

$\begin{array}{l}m\stackrel{⏜}{AB}=m\angle AOB\\ \text{=50}\end{array}$

Therefore, the measure of arc $AB$is $50.$
