Answer :

The length of the segment BC is equal to 5√3 π / 3.

What is the length of a missing side of a geometric system?

Herein we find the a geometric system formed by a circle and an inscribed  right triangle formed by two right triangles. By a quick inspection we find the following measures:

AD = 10π, m ∠ BCD = 60°, m ∠ BDC = 30°, m ∠ BDA = 60°, m ∠ BAD = 30°

Then, by 30-60-90 right triangle theorem we find that:

DB = (1 / 2) · AD

DB = (1 / 2) · 10π

DB = 5π

DB = √3 · BC

BC = (√3 / 3) · DB

BC = 5√3 π / 3

The length of the segment BC is equal to 5√3 π / 3.
