Answer:

First option

x = 9.1, AB  = 16.5, CD = 14.1

Step-by-step explanation:

5 * x = 13 * 3.5

5x = 45.5

x = 9.1

AB = 3.5 + 13 = 16.5

CD = 5 + 9.1 = 14.1

The value of x and the length of each chord is x = 9.1, AB  = 16.5, CD = 14.1. Thus first option is correct.

What is the relation between line perpendicular to chord from the center of circle?

If the considered circle has center O and chord AB, then if there is perpendicular from O to AB at point C, then that point C is bisecting(dividing in two equal parts) the line segment AB.

Or

|AC| = |CB|

Let x be the measure of the length of ED.

[tex]5 \times x = 13 \times3.5\\5x = 45.5\\x = 9.1[/tex]

Therefore,

AB = 3.5 + 13 = 16.5

CD = 5 + 9.1 = 14.1
