Answer:

x = 9

Step-by-step explanation:

You have to use the Secant Segment theorem:

AB * AC = AD * AE

This means that the external piece of the secant times the whole secant for one is equal to the external piece of the secant times the whole secant for the other.

Now, setup an equation:

8(x + 8) = 4(30 + 4)

Simplify:

8x + 64 = 120 + 16

8x = 72

x = 9

Which is true about folding the paper to form a bisector of the segment?

TiliK225 [7]

Answer: option B. The paper crease divides the line segment into 2 congruent segments.

This is true whenever you fold the paper in such a way that the edges of the segment overlap when the paper is folded. Then when you unfold the paper, the crease passes trough the middle of the segment showing two identical (congruent) parts.
