OHHH IT ALL MAKES SENSE NOW OMG THXYou have to solve the angle opposite to the missing side, the angle you just found is opposite to 8 , so minus the answer form the angle you just found from 180 so you do:
180-63-42=75
180(sum of all angles in a triangle)-63(angle you just solved)-42(angle they all ready gave)=75(theta)
