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 ...Protractor. A protractor is a tool used to measure angles. Most protractors measure angles in degrees (°). When using a protractor, notice that the outside set of numbers goes from 0 to 180 degrees where the 0 is on the left side of the protractor while the inner set goes from 180 to 0 degrees where 0 is on the right side of the protractor.The reference angle is the amount of rotation more than 180 the 210 extends into the third quadrant. So the reference angle is calculated by subtracting 180 from 210 . So the reference angle indicated by the the red arc is 210 - 180 = 30 . So that's the answer. The reference angle is always the acute angle between the terminal side and the x-axis.

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°. Find the Exact Value cos(330) Step 1. Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Step 2. The exact value of is . Add +360 degrees until you have a positive angle, then sketch. The reference angle is the angle from the sketch to the x-axis, in this case, 60 degrees. It makes sense here to state the angle in terms of its positive coterminal angle. To find this, add a positive rotation (360 degrees) until you get a positive angle. -240+360=120 Since …
