Apply the reference angle by finding the angle with equivalent trig values in the first quadrant.Find the reference angle for 330 degreesCoterminal Angles are angles who share the same initial side and terminal sides. Finding coterminal angles is as simple as adding or subtracting 360° or 2π to each angle, depending on whether the given angle is in degrees or radians. For example, the angles 30°, –330° and 390° are all coterminal. What is the terminal side?Reference angles. A reference angle is an acute angle (<90°) that can be used to represent an angle of any measure. Any angle in the coordinate plane has a reference angle that is between 0° and 90°. It is always the smallest angle (with reference to the x-axis) that can be made from the terminal side of an angle. The figure below shows an ...

150° is located in the second quadrant. The angle it makes with the x -axis is 180° − 150° = 30°, so the reference angle is 30°.This tells us that 150° has the same sine and cosine values as 30°, except for the sign. We know that. cos ( 3 0 ∘) = 3 2 a n d sin ( 3 0 ∘) = 1 2. This formula allows you to find coterminal angles by adding or subtracting multiples of 360 degrees to the original angle. For example, if the original angle is 150° and you want to find a coterminal angle within one complete revolution (360°), you can calculate: Coterminal Angle = 150° + 360° * 1 = 510°.Trigonometry Find the Reference Angle -330 degrees −330° - 330 ° Find an angle that is positive, less than 360° 360 °, and coterminal with −330° - 330 °.

May 30, 2022 · The reference angle on a unit circle is the smallest, positive central angle formed by the terminal side of the angle and the x-axis.To find the reference angle: Points on the unit circle in ...460°– 360° = 100°. Take note that -520° is a negative coterminal angle. Since the given angle measure is negative or non-positive, add 360° repeatedly until one obtains the smallest positive measure of coterminal with the angle of measure -520°. −520° + 360° = −160°. −160° + 360° = 200°. Standard position of an angle - trigonometry. In trigonometry an angle is usually drawn in what is called the "standard position" as shown below. In this position, the vertex of the angle (B) is on the origin of the x and y axis. One side of the angle is always fixed along the positive x-axis - that is, going to the right along the axis in the ...
