No, just make a new one (if the system lets you)

Your account is not hacked.  

It has not been used for 35 months! 

You just forgot you password.

Don't worry, you didn't sound rude to me :)

I am sorry there is so much frustration at the moment.

Unfortunately I can't fix it.   I know admin is aware of problems but he is having problems fixing them and he is a very busy person.

There are problems with the network.

The owner of the site is trying to work it out.

I am sorry about all the frustration and inconvenience.

Thanks Tiggy.

I assume the accpetable reason is ...

         "The angle between a tangent and a chord is equal to the angle subtended by the chord in the alternate segment."

But I do not remember this rule.  I have to find/see a proof to convince myself that it is true.

I found a good proof on YouTube   

Thanks Tiggsy,  (and it is nice to see you again   )

Why is angle XWZ equal to  angle WYX ?   

this is not a general solution.  BUT

If you let the diameter of the circle be 14 units then WZ will be an altitufde for WXY

By using pythagoras's theorem and a bit of manipulation you can determine that ZX = \(11\frac{3}{7}\)

Here is a geometric solution.  I just wanted to see if the distance actually did always stay the same.

The graph is interactive.  You can right click W or Y and change the triangle.  

The length of ZY stays the same.  Approx   11.43 units

Thanks Geno,

Hi Loona,

Firstly this would have to be a bevy big bag of candy (really of infinite size) otherwise it is not correct to do it this way.

But for a school question you do not have to worry about that. 

Your question for part B looks unfinished.  Maybe some LaTex has been omitted?

Be careful to proofread you questions before you post them.

You made a good start on you tree but in my view it is not finished.
