Answer:
B. 84.46°
Step-by-step explanation:
Since the vectors are at right angles to one another, even a crude diagram will quickly show you that the direction of the sum is ...
30° + arctan(7/5) ≈ 84.4623° ≈ 84.46°
It telling you that your x and y are greater then 0. therefore it would be the first because both your x and y are positive and the third quadrant because when you multiple two negatives it gives you a positive.
Answer: a) b)

And the probability that at least one of the two officers is a woman would be
Hence, a) b)
