D. 45 and can you answer my history please ASAP
I’m confused on what your asking, I can help if you specify
<span>The reference angle is closest to the x-axis.
I will assume the above is 7pi/6. That would be a reference angle of pi/6, and the sin in the 3rd quadrant is negative, so the sin theta = - 0.5</span>
I think the approximate perimeter of the parallelogram is 30 square units. But I am not 100% sure.
Well this is pretty easy, look. First we divide 3/4 (Length of shadow), then we multiply that by 36 (4*9 = 36), then we get 27 as an answer! Hope this helped. Brainliest is always appreciated.
