..

I am supposed to find angle A with a bit of trig and geometric innovation.. but as my flu has only abated now, I have only made these observations..

hi Mathegocart

Sorry to hear about your flu. Hope you're soon feeling better.

I find the key to many geometry problems is a good diagram. Based on those angles your is a bit lop-sided. Is this better?

It shouldn't take long to chase around those angles in right angled triangles. If my diagram isn't correct please would you specify the angles like this DAC = 90 etc.

Thanks,

edit: hhmmm. Mine cannot be right as DM = 10 and MA = 4. Please help correct mine.

Hi;

Get better fast and when you grow up move to a warmer climate like Florida.

bit of trig and geometric innovation

Unnecessary! You can solve for the angle at A easily. Lots of times when those types pose problems the only way they can make it difficult is by providing misleading diagrams. You can defeat that by drawing a good diagram. Either you can call forth the powers of Giotto within or you can use the Gebra.

My headache is alleviating a little bit, atan(10/4).

I do not know what to say... If CM and DA ain't straight lines then this could be a difficult problem...

If they are and I think the way the problem is stated they want them to be...

Then that is what I would do.

My headache is alleviating a little bit...

The number one cause of all headaches is dehydration. Drink plenty of water, no soda, no sweets, no coffee, those all help to dehydrate you further.
