The following is a right pyramid on a square base with side length 12cm. A right pyramid has its apex aligned directly above the centre of its base.

The edge length VA is 23cm.
Now, if the size of \angle VAW is \theta °, find \theta  to two decimal places.
Please directly answer the question and provide the final value, e.g., 1, 2.5, 300.
