Reference Angle Calculator

WebReference Angle. When an angle is drawn on the coordinate plane with a vertex at the origin, the reference angle is the angle between the terminal side of the angle and the x x -axis. The reference angle is always between 0 0 and \frac {\pi} {2} 2π radians (or between 0 0 and 90 90 degrees). In both these diagrams, the blue angle y y is a ... WebJul 12, 2024 · The reference angle is always the smallest angle made from the terminal side of an angle with the x-axis. Angle 120° lies in second quadrant To find the reference angle measuring x° for angle in Quadrant II, the formula is (180−x)° Reference angle= (180-120)°=60° hence, the reference angle is 60° Advertisement h3llobob WebBased on this, the formula for finding the reference angle, $\gamma$ degrees, for a given angle of $\alpha$ degrees varies depending on the value of $\alpha$. ... Therefore, finding the cosecant of $120$ degrees requires finding the sine of $120$ degrees, which can be found using the sine of $45$ and $30$. Since, however, the sine of $90$ was ... shopmycoif
