Convert The Angle $\theta = \frac{257 \pi}{360}$ Radians To Degrees. Express Your Answer Exactly.$\theta = \square$

Understanding the Problem

Converting radians to degrees is a fundamental concept in mathematics, particularly in trigonometry. In this article, we will explore how to convert the angle $\theta = \frac{257 \pi}{360}$ radians to degrees. We will break down the problem into manageable steps and provide a clear explanation of each step.

What are Radians and Degrees?

Before we dive into the problem, let's briefly discuss what radians and degrees are. Radians are a unit of angle measurement that is based on the ratio of the arc length to the radius of a circle. One radian is equal to the angle subtended by an arc of length equal to the radius of the circle at the center of the circle. Degrees, on the other hand, are a unit of angle measurement that is based on a circle being divided into 360 equal parts.

Step 1: Recall the Conversion Formula

The conversion formula from radians to degrees is given by:

$$\text{degrees} = \frac{180}{\pi} \times \text{radians}$$

This formula can be used to convert any angle from radians to degrees.

Step 2: Plug in the Value of $\theta$

We are given that $\theta = \frac{257 \pi}{360}$. We can plug this value into the conversion formula:

$$\text{degrees} = \frac{180}{\pi} \times \frac{257 \pi}{360}$$

Step 3: Simplify the Expression

To simplify the expression, we can cancel out the $\pi$ terms:

$$\text{degrees} = \frac{180}{360} \times 257$$

Step 4: Evaluate the Expression

Now, we can evaluate the expression:

$$\text{degrees} = \frac{1}{2} \times 257$$

$$\text{degrees} = 128.5$$

Conclusion

In this article, we have shown how to convert the angle $\theta = \frac{257 \pi}{360}$ radians to degrees. We have broken down the problem into manageable steps and provided a clear explanation of each step. The final answer is $\boxed{128.5}$ degrees.
