If A,B,C and D are collinear points in order and AD = ( 5x+20) cm ,AB=(x+10) cm, CD= (2x+10) cm, then AC= |

Answer» AC = 3x+10Step-by-step explanation:Given that A,B,C and D are collinear points in order=> AD is the larger LINE segment given by AD = AB+BC+CDie., 5x+20 = x+10 + BC + 2X+10 (measuments given)=> 5x-x-2x = 10+10-20+BC=> 2x = BC ie., BC = 2xalso, we have AC = AB+BC=> AC = x+10 + 2x=> AC = 3x+10 |
