Q11? Don't you think that was more difficult? No one talking about it?

Can someone anyone post the drawing on q11? The circle and the tangent....is really really nagging me..

I'm afraid I messed it up but I don't know how I got to 90-2x in the end. I really have to re do it...so that I can go to bed tonight and get sone sleep...
YES OH MY GOD.

I was like for a Q11 it was a really hard one.

Hoping the next papers don't follow and be as hard.
Answer is 90-2x

it was AOB and AB = 0B as they are radiis both from center so AOB was an isosceles so Angle AOB is equal to 180 - 2x degrees then to find the other side do 180 - (180-2x) = 2x .

since the tangent meets the circumference a right angle is created. so the other angle is 90 degrees. to find the angle ACB do 180 - (2x +90) = 90+ 2x you cant simplify that into 45 + x so pls dont think tht since 45 + x is a completely different value for angle

Yeah I did it here. Don't worry I messed it up in the exam though
Here it is. Feel free to ask if you don't get any of the labelling.

Got 90-2x, but I just hope my reasons were actually correct.

You halved it 😥. If x was 2, 14-2x is not equal to 7-x but youll only drop one mark
looks like i didnt need to just redo it then...
