Reference to a standard normal distribution table shows that for a cumulative probability of 0.6064 the z-score is 0.27.
Angles around a point equal 360°, so n = 360 - 291 = 69°
Thus, as angles in a triangle add to 180°, m = 180 - 31 - 69 = 80°
If you Just divided -11u and 44 by -11 u equals 4
You’re answer is B, you just have to multiply all of the sides together and then add your sums.
Hope this helps:)
