Web30°- and 60°-Angle Values (from a 30-60-90 triangle) When we need to work with a 30 - or a 60 -degree angle, the process is similar to the above, but the set-up is a bit longer. (A 30° angle is equivalent to an angle of \frac {\pi} {6} 6π radians; a 60° angle is equivalent to an angle of \frac {\pi} {3} 3π radians.) WebIn trigonometry we use the functions of angles like sin, cos and tan. It turns out that angles that have the same reference angles always have the same trig function values (the sign may vary). So for example sin (45) = 0.707 The angle 135° has a reference angle of 45°, so its sin will be the same. Checking on a calculator: sin (135) = 0.707
