ABC is a equilateral triangle .
Proof :-
Let's assume both circles as C1 and C2 [ as shown in the figure ]
- AB is the radius of circle C1
- AB is the radius of Circle C2
AC is the radius of circle C1.
BC is the radius of circle C2 .
AB and AC both are radius of circle C1 so both are equal ie AB = AC .
AB and BC both are radius of circle C 2 so both are equal ie AB = BC .
Hence we conclude that .
AB = BC = AC.
So the triangle is equilateral triangle.

Answer:
A
Step-by-step explanation:
You can solve this problem by setting up a ratio. 5 pounds of flour makes 120 muffins, so the ratio of pounds of flour to muffins is 5:120=1:24. This means that you can make 24 muffins with 1 pound of flour. Multiplying both of these by 2, you get 24*2=48 muffins with two pounds of flour, or answer choice A. Hope this helps!
Answer:
Step-by-step explanation:
A =1/2 *h (x+y)
A =hx+hy/2
A*2 =hx+hy
2A =hx+hy
2A - hy = hx
(2A -hy)/h = x
