Chapter 13: Q. 37 (page 713)

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

Short Answer

Expert verified

The degree measure of angle $- \frac{π}{4}$ is $- 45 °$ .

Step by step solution

Step 1. Write down the given information.

The given angle in radian measure is $- \frac{π}{4}$ .

Step 2. Concept used.

From the degree – radian conversion rule.

$π Radian = 180 {}^{\circ}. . . . (1)$

Step 3. Convert degrees measures to radians.

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

$\begin{array}{l} - \frac{π}{4} = - \frac{1}{4} (π) \\ = - \frac{1}{4} \times (180^{°}) \\ = - 45^{°} \end{array}$

Step 4. Conclusion.

The degree measure of angle $- \frac{π}{4}$ is $- 45 °$ .
