Why is H3O+ bond angle 109.5?

Question: Why does H3O+ have an angle of 109.5 degrees, making it a tetrahedral? Should it not be a trigonal planar?

Answer: Electron pairs count as a region of electron density.

H3O+ structure. Lp stands for lone pairs.

Why is it a tetrahedral and not a trigonal planar? Are there other examples of this other than with H3O+?
