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


AE*EC=BE*ED

now, we can plug values


(x+1)*(x+3)=(x)*(x+10)

now, we can multiply them


x^2+4x+3=x^2+10x

now, we can move all terms on left side


x^2+4x+3-x^2-10x=0


3-6x=0


x=(1)/(2)...............Answer
