Answer:
Step-by-step explanation:
10 cups
2/8=10/x
2x=80
X=40cups
40 cups
2/8=40/x
2x=320
X=160
8 cups
2/8=8/x
2x=64
X=32
we are given
BE=x
ED=x+10
AE=x+1
EC=x+3
we can see that two chords AC and BD are intersecting inside the circle
so, we can use property

now, we can plug values

now, we can multiply them

now, we can move all terms on left side
