Find x if:<br> - B is between A & C;<br> -AB = x + 5;<br> -BC = 2(x-3); and<br> -AB ~= BC

aliya0001 [1]

Answer:

The value of x = 11

Step-by-step explanation:

Given

B is between A and C.

AB = x+5

BC = 2(x - 3)

${\overline {AB$ ≅ ${\overline {BC$

Determining the value of x

As B is between A and C, so

${\overline {AB$ ≅ ${\overline {BC$

AB = x+5

BC = 2(x - 3)

x + 5 = 2(x-3)

x+5 = 2x-6

2x-x = 5+6

x = 11

Therefore, the value of x = 11
