What is the sine value of 7 pi over 6? negative square root 3 over 2 square root 3 over 2 negative 1 over 2 1 over 2?
djverab [1.8K]
First thing to do is to change the radians to degrees so it's easier to determine our angle and where it lies in the coordinate plane.  \frac{7 \pi }{6} * \frac{180}{ \pi }=210.  If we sweep out a 210 degree angle, we end up in the third quadrant, with a 30 degree angle.  In this quadrant, x and y are both negative, but the hypotenuse, no matter where it is, will never ever be negative.  So the side across from the 30 degree reference angle is -1, and the hypotenuse is 2, so the sine of this angle, opposite over hypotenuse, is -1/2

If you look closely the area where 3x is congruent to the other side of the 90 degree angle with one part as 0.5x + 34

So
3x + 0.5x + 34= 90

x will be 16

So plug it in

0.5(16) + 34= 42 degrees


And


3(16)= 48 degrees

That left half of the circle is 180 degrees and since we know the angle 3x is 48 degrees we subtract it from 180 to get angle AE


180-48

132 degrees is your answer
