Need quick ? ! using the angle bisector theorem solve for x. show all work.

Using the Angle Bisector Theorem solve for x.

The "Angle Bisector" Theorem says that an angle bisector of a triangle will divide the opposite side into two segments that are proportional to the other two sides of the triangle.

As, we see the figure, AD bisects angle A

So, Applying Angle Bisector theorem, we get,

15 divide by 3 gives 5

So, we have

5=

To get rid of fractions let us multiply by 5 on both sides

5*5=

25=

25=4x+1

To solve for x, let us subtract 1 from both sides

25-1=4x+1-1

24=4x+0

Or, 4x=24

To solve for x, let us divide by 4 on both sides

x=6

x=6
