Yet Another Suncatcher

A glass suncatcher is in the shape of an equilateral triangle with sides of length \(144\text{ mm}\). The triangle is labeled \(ABC\) and divided into \(8\) smaller sections as follows.

One of the sections is coloured blue, as shown. An altitude is constructed from \(A\) to \(D\) on \(BC\), dividing the blue section into two parts.

Triangle ABC has side BC horizontal, with B to the left of C, and altitude AD vertical. The section of the triangle that lies between the 5th and 6th line segments, counting from vertex B, is coloured blue.

In the blue section, determine the ratio of the area on the left side of the altitude to the area on the right side of the altitude.
