To find x, substract 72 and 78 from 180 since all triangles are 180°

180 - 72 - 80 = 30

So x = 30

To find y, x and y equal 180 so subtract 30 from 180

180 - 30 = 150

y = 150

x = 30, y = 150

3200≥1200+600+675 Because, the phone plan only allows at maximum 3200 minutes, meaning that all of the minutes the family has used has to be less than or equal to 3200 minutes (Or 3200 minutes is greater than the amount of minutes used by the Cruz family)
