fixed,polar mount and C band dish.

Kindly refresh my 88 year old memory regarding the inclination angle for the subject dish.
I am in South Africa my latitude being 34.39.My inclination angle is 5.
Do I set the dish angle at 39.39.
 
If I understood you correctly
90-34,39=55,61
 
I assume you are using a prime focus reflector. If not then the manufacturer would have an offset angle within the specifications

My elevation is 47.91 how would I measured it against the pictured dish.

Where did you get that elevation value from? You are still at LAT = -34.4?

In that case your total elevation due south north is 50.0 degrees.
Dish face angle, taking into account the 22.6 degrees offset angle of the dish, would be 50 - 22.6 = 27.4 degrees.

Edited: due NORTH

When dish declination offset angle is 5.0 degrees, you are (correctly!) using modified motor angles.
Modified motor-axis elevation then is 55.0.

Total dish elevation is 55 - 5 = 50.0 degrees (dish face angle, for a prime focus dish). (For an offset dish, dish face angle must be corrected with the offset angle of the dish.)

This angle of 50 degrees is when 0 degrees is at horizon, and elevation = looking 50 degrees up.
When you use 90-50 = 40.0 degrees, that is when you start with vertical = 0 degrees, and then looking 40 degrees down.

I hope this helps?
