i measured the angle two time every 3rd day and the noon sun angle was about 29 to 30 degrees but today it was less than this so how come one day its 29 and other day it's 30 and the third say it went back to 28
please answer my question

It depends on the time of year and wether you are located in the Northern or southern Hemisphere. For those of us above the
Equator the angle keeps getting lower till dec 22nd(the winter solstice) then starts getting larger and larger till the summer solstice(june 21st) Just the opposite occurs for those in the southern hemisphere

Hi. Your words "the noon sun angle was about 29 to 30 degrees" implies a quite large margin of error in your measurements. This is part of the problem. The other part is that the Sun SEEMS to be highest at noon it is usually not due to our use of time zones and clocks. If you measure not the height at a certain time but the actual highest point in the sky (local noon) your readings will be much more accurate.

The problem could be the observer (you)...
To get good numbers you need to measure using two fixed objects, like poles driven into the ground...
Then you will not see large changes from day to day...
Also you should use a good time source like universal time which is a constant..

the angle should be getting lower now, it will be lowest on Dec.22nd, then start increasing.
this happens b/c earth axis is tilted, and earth moves around the sun.
