(b) If you do not sleep late, you will not miss class.
(c) If a star does not revolve around the sun, then it is not a planet.

To find the inverse of $A\implies B$, we negate $A$ and $B$. Thus, the inverses are:
(a) If $X$ is not a mouse, then $X $ is not a rodent.
(b) If you do not sleep late, you will not miss class.
(c) If a star does not revolve around the sun, then it is not a planet.
