What Is The Angle Of Smallest Positive Measure Coterminal With 520°?
Introduction
In mathematics, angles are measured in degrees, and a full circle is equal to 360°. When dealing with angles, it's essential to understand the concept of coterminal angles, which are angles that have the same terminal side. In this article, we will explore the angle of smallest positive measure coterminal with 520°.
Understanding Coterminal Angles
Coterminal angles are angles that have the same terminal side but differ by a multiple of 360°. This means that if we add or subtract a multiple of 360° from an angle, we will get an angle that is coterminal with the original angle.
Calculating Coterminal Angles
To calculate the coterminal angle of a given angle, we can use the following formula:
coterminal angle = given angle - (360° × integer)
where the integer is a whole number that we can add or subtract to get the coterminal angle.
Finding the Angle of Smallest Positive Measure Coterminal with 520°
To find the angle of smallest positive measure coterminal with 520°, we need to subtract a multiple of 360° from 520° until we get an angle between 0° and 360°.
Let's start by subtracting 360° from 520°:
520° - 360° = 160°
Since 160° is still greater than 360°, we need to subtract another 360°:
160° - 360° = -200°
However, we want to find the angle of smallest positive measure, so we need to add 360° to -200°:
-200° + 360° = 160°
Therefore, the angle of smallest positive measure coterminal with 520° is 160°.
Example
Let's consider an example to illustrate the concept of coterminal angles. Suppose we have an angle of 520°, and we want to find the angle of smallest positive measure coterminal with it.
Using the formula above, we can calculate the coterminal angle as follows:
coterminal angle = 520° - (360° × 1) = 520° - 360° = 160°
Therefore, the angle of smallest positive measure coterminal with 520° is 160°.
Conclusion
In conclusion, the angle of smallest positive measure coterminal with 520° is 160°. This is calculated by subtracting a multiple of 360° from 520° until we get an angle between 0° and 360°. Understanding coterminal angles is essential in mathematics, and this concept has numerous applications in various fields, including trigonometry, geometry, and engineering.
