Chapter 12.2, Problem 7CYU

To determine

Find the degree measure or radian measure as per the given degree or radian.

Answer to Problem 7CYU

The degree measure is ${45}^{\circ }$ .

Explanation of Solution

Given: It is given in the question that the radian is $\frac{\pi }{4}$ .

Concept Used:

In this, use the concept of multiplying by $\frac{180}{\pi }$ to convert radian to degree and when convert to degree into radian multiply by $\frac{\pi }{180}$ .

Calculation: Here, the radian will be $\frac{\pi }{4}$ .

Now, multiplying it by $\frac{180}{\pi }$ ,

  $\frac{\cancel{\pi }}{4}\times \frac{180}{\cancel{\pi }}={45}^{\circ }$

Conclusion:

The degree measure is ${45}^{\circ }$ .
