Observations were made for two angles and as follows:<image 1>Determine the adjusted values of $\alpha$ and $\beta $.
['$\\alpha$ = 20°10\'11.82",$\\beta $ = 30°20\'34.73"', '$\\alpha$ = 20°10\'11.82",$\\beta $ = 30°20\'38.73"', '$\\alpha$ = 20°10\'11.82",$\\beta $ = 30°20\'32.73"', '$\\alpha$ = 20°10\'11.82",$\\beta $ = 30°20\'22.73"']
