WebWithout using a calculator, compute the sine and cosine of 5pi/4 by using the reference angle. If 0 =1pi/6, then If 0= -2pi/3, then If 0= -5pi/4, then Find an angle 0 with 0° < 0 < 360° that has the same: 1225 5. 54. 00 = 2250 What is the reference angle? 4 radians-> 2250-1880 = 150...: π In what quadrant is this angle? 3 Sin (54/4)-2 2 COS ... WebSolution: First, we will convert the given angle in radians: Angle In Radians = Angle In Degrees ∗ π 180. Angle In Radians = \ (123o\) ∗ 3.14 180. Angle In Radians = 2.145rad. …
