Question from Dimaris, a student: The radius of the outer circle of 2 concentric circles is x. An equilateral triangle inscribed in the outer circle also circumscribes the inner circle. What is the radius of the inner circle in terms of x? |
Hi Dimaris,
I can help you get started.
In my diagram the length of BC is x. What are the measures of the angles in triangle ABC?
