Q2. - Geometry

Question

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

 $\stackrel{⏜}{AB}$

Step-by-Step Solution

Answer

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

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 $50.$
