Answer:
Area=
Step-by-step explanation:
Area of circle is given as:

Where 
To find radius of a circle circumscribing an equilateral triangle, we use the expression

Where, a is the length of sides of the equilateral triangle. Therefore:-
We can then proceed and calculate the area of the circle as follows:-

*The attached picture illustrates what the circumscribed equilateral triangle looks like
Answer:
The answer to this question is angles
Eliminationg these equations gives zero ,no solution
