For the circle question, I will show you a picture with working on, angles and lines etc which may help you solve/understand this theorem.

Using the angles on the diagram, write down what you know and see if you can come to a conclusion

I cant read a lot of the writing so enlarge it because the writing is cropped

All I’ve done is create a perpendicular bisector from the top of the triangle to the base. Then I’ve just labelled angles different letters.

All you have to do is fill in what you know about angles and the letters and you should come to a conclusion.

For example:
a plus b=180
What is x in terms of a?
What is y in terms of b?
Etc...

Ive done that now but I just don't know if that will get any marks because I haven't linked it to the actual angle

Yes although I’m using my phone (whether that makes a difference I don’t know)
