I don't understand using an exact value for area of quadrilateral AOBC (9√3), but then using an approximate value for area of sector OAB (9.426 instead of 3π). Area (yellow shaded area) = 9√3 − 3π ≈ 6.164
Let's consider an equilateral triangle ABC with a side length equal to 'a'. If a perpendicular line is drawn from one of the vertices, to the side of the triangle, the perpendicular line divides the 60° angle at the vertex and the side of the triangle into two halves, that is 30° and a\2. the a/2 is the side opposite 30°, and the longest side is opposite the 90° formed by the perpendicular line and the side of the triangle remains a.

(3)^2=9 60°/9=6.6 2^3.2^3 2^1.1^3 2.3(x ➖ 3x+2).
Can you clarify how the side of the largest angle is twice the size of the side of the smallest angle?

You can apply trigonometry and can realise it easily 🎉
