Thanks again :)

Good evening Candice! Another way is to connect A to O (I have labelled four points A, B, C and O in my diagram) so that we can focus on isosceles triangle AOC.

From there, we can find our wanted angle ABC using the angle at the centre is twice the angle at the circumference property.
