I believe y = 90°

Step-by-step explanation:

70 + 110 = 180, so you know that both sides are the same angle. The angle of the two straight lines must be 90°

28%

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.

Percent of catalogues received = 100% - percent of magazines received

100 - 22 = 78%

Percent of clothing catalogues = 0.78 x 36 = 28%
