Can you please also help me with this problem too?

Segment

Hi DarkTangent,

I have fixed your LaTeX -- on this forum, you can type LaTeX inside [math] tags rather than dollar signs.

You can find some useful information here.

Thanks! That helped a lot.

hi DarkTangent

I find it best to get a really good diagram first.  I use some software called Sketchpad but you can also use geogebra which is free.

In the first question you can write an equation for DA in terms of ED, and then CD in terms of ED.  Add and re-arrange to get ED.

In the second you should be able to work out YOX.  The angle at the edge, YZX, is half this using angle properties of a circle.

On it!
