If b is the midpoint of line ac, ac=cd, ab=3x+4, ac=11x-17, and ce=49, find de

DE=11 UNITS

Step-by-step explanation:

Given AC=CD

And AC=2AB as B is the mid point of AC

Hence 2(3x+4)=11x-17

6x+8=11x-17

11x-6x=17+8

5x=25

x=5

Hence AC=11(5)-17= 55-17=38

AC =CD = 38

CE = 49

Hence DE = CE-CD= 49-38 = 11

segment bisector

step-by-step explanation:

line segment bisector. definition: a line, ray or segment which cuts another line segment into two equal parts. try this drag one of the orange dots at a or b and note the the line ab always divides the line pq into two equal parts.
