Latitude longitude extent of Greece?

formula of latitudes & longitudes.

Someone gave me these coordinates: 28D52'49.71"N & 99D07'00.89" WI know what the numbers mean, but there's no way for me to look those coordinates up on google earth because it uses a different latitude/longitude format. Can anybody help me figure out how to find where these coordinates are?

1.You use an instrument called a sextant and find the following angles of the North Star or Southern Cross above the horizon. At what latitude are you for each? (Don’t forget to mention N or S) Observation: North Star (Polaris) is 5 degrees above horizon=Southern Cross is 23 degrees above horizon=Southern Cross is 89 degrees above horizon=North Star is directly above you=North Star is located on the horizon(After "=" goes "Your latitude" which is the response)2.Using an accurate clock and setting your watch for local noon at your home port, determine your longitude given the following information: Note: Miami Longitude is 80°W, San Diego Longitude is 110°W. (Don’t forget to mention E or W)Observation:You leave Miami and local noon shows 11am=You leave Miami and local noon shows 8am=You leave San Diego and local noon shows 2pm=You leave San Diego and local noon shows 5pm=(After "=" goes "Your longitude" which is the response)
