Hi!
From what I can see you are using mymaths. Before you click the actual work there should be an option to revise or have a lesson on the subject. If that doesn't help I have got some circle thereom notes I have done.

Hi I’ve already been through it but the questions have got significantly harder and I can’t do them.

Can you attempt any of these?

Look at the 1st one. The angle labelled x is subtended by a certain arc of the circle. What other angle is subtended by that arc? Can you work out that other angle using information that you're given in the question? What do you know about angles subtended by the same arc in a circle?

I would also advise then to watch corbett math videos on them

Would x=37°?

That looks good I presume you did 180 - 110 - 33 to get 37 in one triangle, then used a circle theorem to deduce that x = 37 also.

So you see you can do it when you try

Have a go at another one.

Would the second one across be 31°

Hmm I get something different but that's just trying to do it in my head while watching the news

Can you write out your working and what theorems / principles you used to get 31?

I didn't get that - what is the obtuse angle in that triangle with x?

So far these are my answers. I’m struggling with the bottom right and still unsure if others are correct.
