Methane is a tetrahedral shape and those angles are 109.5 degrees.
NH3 is tetrahedral electronic geometry with a lone pair of electrons. The lone pair repels the three H atoms so the angle is a little less than the 109.5.
H2O has two lone pairs so the repulsion is more so. The angle is even less than that of NH3.
