How to solve for the reference angle
WebTo find a coterminal of an angle, add or subtract 360 360 degrees (or 2π 2 π for radians) to the given angle. Reference angle is the smallest angle that you can make from the … WebThus, you multiply both sides of the equation by DG" DG sin (72) = 8.2 "Again because we're solving for DG, we have to isolate DG so that it alone is on the left side of the equation. To do so, we have to move sin (72) to the other side, or in other words divide both sides of the equation by sin (72)." DG = 8.2/sin (72) "Now use the calculator"

WebSep 21, 2012 · 0. I understand perfectly how to find the reference angle for a degree, such as 150 degress = reference angle of 30 degrees, because the 2nd quadrant goes from 90 to 180 degrees, so you simply subtract 150 from 180 to come up with 30. I get that: 11pi/4 = 495 degrees. 495 degrees will give you a reference angle of 45 degress.
