The structural formula of butane is CH3CH2CH2CH3.
All the carbon atoms are bonded to 4 neighbouring atoms tetrahedrally.
Just imagine that you are the carbon atom and you are in the centre of a triangular based pyramid.
The four neighbouring atoms attached to you are at the four corners of the pyramid.

All the bond angles will be 109.5 degree.

The same applies to methane, ethane and propane.
