The z component can be found from the ellipse equation
[math]z=-cot(65^{\circ})x+2.53=-cot(65^{\circ})(.7870)+2.53=2.1623\ \text{cm}[/math]
[math]e\equiv \frac{sin(25^{\circ})}{cos(20^{\circ})}=0.96447[/math]
[math]r_{D1}=R_{Lower\ Dandelin}cos(\theta)=(ae-\Delta a) tan(65^{\circ})cos(\theta)\qquad \qquad r_{D2}=R_{Lower\ Dandelin}cos(\theta)=(ae+\Delta a) tan(65^{\circ})cos(\theta)[/math]

The height to the first directrix circle is
[math]z_{D1}=r_{D1} cot(\theta)=.5901cot(20)=1.6212[/math]
and the x and y components are
[math]x_{D1}=r_{D1}\ cos(\phi)=.5901 cos(0)=.5901\text {m}\ \ \ \ y_{D1}=r_{D1}cos(\phi)=.5901 sin(0)=0[/math]
The height to the second directrix circle is
[math]z_{D2}=r_{D2} cot(\theta)=1.3055cot(20)=3.5868\ \text{m}[/math]
and the x and y components are
[math]x_{D2}=r_{D2} cos(\phi)=1.3055cos(0)=1.3055\text {m}\ \ \ \ y_{D2}=r_{D2} sin(\phi)=1.3055sin(0)=0[/math]
The distance between the two point
[math]\sqrt{(1.3055-.5901)^2+(0-0)^2+(3.5868-1.6212)^2}=\sqrt{.715^2+1.9656^2}=2.09\text {m}[/math]
This should be equal to 2a
[math]2a=2(\frac{a_1+a_2}{2})=2(\frac{.8684+1.2234}{2})=2.09\text {m}[/math]
This gives the components for a point on the directrix circles as
