Test TOMORROW PLEASE HELP ME! Telescope!!!

1. Homework Statement
I need serious help! I have a test tomorrow and I am having trouble with microscope/telescope questions....

A person is designing a 10X telescope is limited to a length of 20 cm, what is the approximate focal length of the objective?


2. Homework Equations



3. The Attempt at a Solution
M = 10X
L = 20 cm
Fo = ???

The equation I found for a telescope is M = -Fo/Fe and the rest of the equations involve theta which I don't have. And I don't have Fe???
