If b is the midpoint of ac, ac=cd, ab=3x+4, ac=11x-17, and ce=49, find de
2 answers:
Answer:
de=11
Step-by-step explanation:
We are given that b is the midpoint of ac
ac=cd, ab=3x+4,ac=11x-17 and ce=49
We have to find the value of de
b is the midpoint of ac therefore we have
ab=bc
ac=ab+bc=ab+ab=2ab





Then , substitute the value of x

ac=
ce=cd+de
49=38+de

de=11
First, we draw our line.
|------------------------------------------------------------------------------------|
a e
Next, break up this line into segments using the information.
|----------------------|----------------------|--------------------|------------------|
a b c d e
The entire line is 29.
ab + bc + cd + de = ae
ab + bc + cd + de = 29
You also know that
bd = bc + cd
Due to midpoint theorem,
ab = bc
cd = de
Then,
2ab + 2cd = 29
The equations we will use are
bd = bc + cd eq1
2bc + 2cd = 29 eq2
Dividing both sides of the equation in eq2 yields
bc + cd = 14.5
bd = bc + cd
bd = 14.5
