An isosceles triangle, a triangle with two sides of equal length has a perimeter of 20 inches. Each of the equal sides is one inch longer than the third side. Find the length of the three sides.

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .

the circumference is c≈245.04

answer is  

c.

56

hope you get this right
