Need help to calculate ELLIPSES.

I have a big problem which I am trying to solve with great difficulty.

I have a ellipse (ellipse #1) in which the angle of orientation is known, I know the length of the major/minor axis in ellipse #1.

Now I am able to calculate the angle of inclination of the next ellipse with a small formula (ellipse #2) but would like to find a way to calculate the length of the major and minor axis's from the termination point of ellipse 1 using the data from ellipse #1 with the only exception being the angle of inclination which i already have calculated,, in other words the lengths at the extremes for ellipse 2 using major axis data from ellipse 1,

Also I want to calculate the length and angle of the minor axis's compared to the major axis's.

In my example right now I am using the formula to calculate the length of an arc which is (2*pi*r)*angle/360. Basically it swings an arc to the extreme ends of the major axis. But I frankly don't know if this is right or not..

If kind enough to respond then please use number examples and simplify your response ie. mathematically. My brain is frazzled!
