With
we find the mean is
and the variance is
Then as , we find that . Simply put, the failure of the CLT/LLN has to do with the fact that the are not independent.
Law of Sines
b/sin(B) = a/sin(A)
b/sin(48) = 50/sin(58)
b = sin(48)*(50/sin(58))
b = 43.8150164386619
b = 43.8
The answer is choice B) 43.8
I think it is either -7/3 or 7/2
I got 37....because 180 - 143 = 37.....
