Показать описание
Learn how to solve problems with chords. A chord is a line that has its two endpoints on the circle. A chord passing through the center of the circle is refered to as the diameter of the circle. A chord divides the circle into two portions: major and minor segments and also divides the cirumference of the circle into the major and the minor arc.

When two chords intersect inside a circle, the relationship between the two chords is that the product of the lengths from the point of intersection to the two endpoints for one chord is equal to that of the other chord.

The answers got covered by the video thumbnails at the end :(

Edit: 15 x 12 = 18 x
180 = 18x, divide both by 18
x = 10 is the answer
