Q. 11 - Algebra 2

Question

 Rewrite each degree measure in radians and each radian measure in degrees if the angle is $\frac{3\pi }{4}$.

Step-by-Step Solution

Answer

The degree measure of angle $\frac{3\pi }{4}$is $135°$.

Step 1. Write down the given information.

The given angle in radian measure is $\frac{3\pi }{4}$.

Step 2. Concept used.

From the degree – radian conversion rule.

$\pi \text{Radian}=180{}^{\circ }....\left(1\right)$

Step 3. Convert degrees measures to radians.

The angle $\frac{3\pi }{4}$in degrees units is evaluated with the help of concept (1) stated above.

$\begin{array}{l}\frac{3\pi }{4}=\frac{3}{4}\left(\pi \right)\\ =\frac{3}{4}\times \left({180}^{°}\right)\\ ={135}^{°}\end{array}$

Step 4. Conclusion.

The degree measure of angle $\frac{3\pi }{4}$ is $135°$.
