19. 60* - a straight line is 180* - the other side which is 120* (supplementary) 20. 132* - the angle below is the same as the other side of this angle, 180* - 48* (same side interior angles) 21. 48* - these are the same angle just in different placements (corresponding angles) 22. 70* - same angles just different placement (alternate interior angles) 23. 85* - these are vertical angles so they’re the same 24. 114* - same angle just different placement (alternate exterior angles)
Actually the answers A since t is for text messages and it costs .15 and m is minutes and costs .07 so we add those two together to he .15t+ .07m then there's a discount of 2.50 so we subtract. So our final equation is .15t + .07m - 2.50 = C
