Answer:
135°
Step-by-step explanation:
a supplementary angle is equal to 180°. since you already have the measure of ZA, all you need to do is subtract 45°, the measure of ZA, from 180°, the total measure of a supplementary angle, in order to figure out the measure of ZB.
180 - 45 = 135, therefore the measure of ZB = 135°.
To find the total people, divide the number of people that made a purchase by the percentage:
45 / 0.30 = 150 people entered.
