Hello, I need help with this problem please (this is counted as large part of my grade so please hel) thank you
Problem:
Each of three congruent circles has radius 1, and each is externally tangent to the other two. An equilateral triangle circumsribes this configuration, so that each circle is tangent to two of the sides of the triangle. What is the perimeter of the equilateral triangle?
Here is my diagram. Please excuse me of my badly drawing scale TT
