Answer

\angle EFD = \angle DFB = \angle BFA = 90^\circ$.

Here's a step-by-step solution for Question 9.

Given Information:

Circle ABCDE.
AC is a chord.
$AFD \perp EFB$ , which means the lines $AD$ and $EB$ intersect at $F$ at a $90^\circ$ angle. So, $\angle AFE = \angle EFD = \angle DFB = \angle BFA = 90^\circ$ .
$\angle D1 = 40^\circ$ , which is $\angle ADE = 40^\circ$ .
$\angle E = \angle B1$ , which is $\angle AED = \angle ABC$ .
