**[GR 11] Find the exact value of cos120 without a calculator**

4/06/2010 · Best Answer: U want the exact values so use the 2, √3, 1 right triangle (60° is opposite the √3 side, 30° is opposite the 1 side and the hypotenuse is 2) to get: sin 120 = sin (180 - 60) = sin 60 = √3 / 2 [sin and cosec are positive in the 2nd quadrant]... Complementary angles – if sum of any of two angles are equal to 90 degree, then both angles are known as a complementary angles like if angle ‘A’ and angle ‘B’ are two complementary angles, then if angle ‘A’ is of 30 degree, then angle B is 90 – 30 = 60 degree.
