How do we pronounce the connection between mohâsebe kardan (calculating) and zâviye (angle)?

You need to add an invisible ezafe (an -e sound) to the end of the infinitive, pronouncing it mohâsebe kardan-e zâviye. Because the compound verb mohâsebe kardan is being used as a noun here (a gerund meaning the act of calculating), it acts like a regular noun that possesses the angle. Think of it literally as the calculating of the angle.

Is the word didgâh made up of smaller parts?

Yes! It combines did (sight or vision, coming from the past stem of didan, to see) with the suffix -gâh, which denotes a place. Literally, it means a viewing place or vantage point, which is why it translates so perfectly to perspective or standpoint.
