Chapter 9: Q6. (page 341)

In exercises $2 - 7$ find the measure of the arc.
$\overset{⏜}{C D A}$

Short Answer

Expert verified

The measure of an arc $\overset{⏜}{C D A}$ is $230 .$

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

$\begin{array}{l} ∠ C D A = 360^{\circ} - ∠ A B C \\ {=360}^{\circ} - 130^{\circ} \\ =23 0^{\circ} \end{array}$

Since

$\begin{array}{l} m \overset{⏜}{C D A} = m ∠ C D A \\ =230 \end{array}$

Therefore, the measure of arc $C D A$ is $230 .$
