WebMar 26, 2016 · Find the reference angle. Using the top chart, you can see that a 300-degree angle has its terminal side in the fourth quadrant, so you find the reference angle by subtracting 300 from 360. Therefore, the measure of the reference angle is 60 degrees. Find the numerical value of the tangent. WebReference Angle Angles can be more than 90º But we can bring them back below 90º using the x-axis as the reference. Think "reference" means "refer x" The simplest method is to do a sketch! Example: 160º Start at the positive x axis and rotate 160º Then find the angle to the nearest part of the x-axis, in this case 20º
