This is the last one that I need help with. @Will.H
OpenStudy (sshayer):
<AEB+2<CED=180
OpenStudy (will.h):
<BEC = <CED we need to find BEC and AEB and then add them 4x + 1 + 4x + 1 + 11x - 12 = 180 19x - 10 = 180 19x = 190 x = 10 find BEC: 4x + 1 4(10) + 1 BEC = 41 Find AEB: 11x - 12 11(10) - 12 AEB = 98 now add them to find AEC AEC = AEB + BEC AEC = 98 + 41 AEC = 139
