Answer:
isoceles but not equilateral
Step-by-step explanation:
it has two sides that are the same length, but not all three sides are the same length
An equilateral triangle is therefore a special case of an isosceles triangle having not just two, but all three sides equal
let's find the area of the outer circle and the inside circle
the inside's circle area
A= π x 6²=36π
the outer's
A' = π x 4x²= 4πx²
A'-A=4πx²- 36π=160πcm² equivalent to x²- 9=40, so x²=49 implies x =sqrt(49)=7, x=7.
