This is the textbook question. I do not have the solution. I am pretty stuck on this one

My attempt on this...find my rough sketch here;

From my analysis;

##x+x+m+m=180^0## angles opposite each other on a cyclic quadrilateral... I have point ##O## as the centre of the circle.

##x+y+z+x+y+z=180^0##

##⇒2(x+y+z)=180^0, x+y+z=90^0## therefore ##∠DEB= ∠AEB = 90^0##

Also i know that;

##AB⋅AC= AE⋅AD##
