WebSolution. 150° is located in the second quadrant. The angle it makes with the x -axis is 180° − 150° = 30°, so the reference angle is 30°.This tells us that 150° has the same sine and cosine values as 30°, except for the sign. We know that. … WebTricks to Find Reference Angles: We use the reference angle to find the values of trigonometric functions at an angle that is beyond 90°. For example, we can see that the coterminal angle and reference angle of 495° are 135° and 45° respectively. sin 495° = sin 135° = +sin 45°. golf games for ps3
