2020年10月10日 · The value of sin 30 degrees and sin 150 degrees are equal. Both are equal because the reference angle for 150 is equal to 30 for the triangle formed in the unit circle. The reference angle is formed when the perpendicular is dropped from the unit circle to the x-axis, which forms a right triangle.

Discuss the accuracy of the recorded acceleration.

2019年4月14日 · Calculate sin (150)° Since our angle is greater than 90 and less than or equal to 180 degrees, it is located in Quadrant 2 In the second quadrant, the values for sin are positive only. 150 is an obtuse angle since it is greater than 90° sin (150)=1/2

2020年7月23日 · Explanation:Hey usersin (150) = sin (90 + 60) = sin (90 - 60) = sin (30) = ½. So, sin 150 =1/2.Hope it helpsplease mark it as brainliest
