Find x if:<br> - B is between A &amp; 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)
  • {\displaystyle {\overline {AB} ≅ {\displaystyle {\overline {BC}

Determining the value of x

As B is between A and C, so

{\displaystyle {\overline {AB} ≅ {\displaystyle {\overline {BC}

as

  • AB = x+5
  • BC = 2(x - 3)

so

x + 5 = 2(x-3)

x+5 = 2x-6

2x-x = 5+6

x = 11

Therefore, the value of x = 11

Given circle N with chord AB, which point lies on the perpendicular bisector of AB?
aivan3 [116]

The point that lies on the perpendicular bisector of AB is point N

<h3>How to determine the point?</h3>

The circle is given as:

Circle N

The chord is given as:

Chord AB

The perpendicular bisector of the chord is any line drawn from the center of the circle that divides the chord in equal halves.

This means that the point starts from point N

Hence, the point that lies on the perpendicular bisector of AB is point N
