P(A) means "Probability of Event A" The complement is shown by a little mark after the letter such as A' (or sometimes Ac or A): P(A') means "Probability of the complement of Event A" The two probabilities always add to 1.
162 is not a perfect square therefore you have to find the largest perfect square that can go into 162 which would be 81.

Answer:
3.6 minutes.
Step-by-step explanation:
According to the data given in the question, between 9 and 10 AM, 220 passengers have checked in which means that the check-in rate is 3.6 passengers per minute. If the average number of passengers waiting for check-in is 32 and if we assume that the check-in rate is constant throughout the day, then the average passenger had to wait in line for 3.6 minutes.
Y is same as the missing angle, the triangle need to equal to 180 so if you add 20 to 60 it equal to 80
use 180 to subtract to 80 you will get the missing x, x=80
