how can i enter angle 20 deg ,30 min

Hello, Masoud!

Minutes and seconds of degrees are like minutes and seconds of an hour. To find, say, 30 deg, 15 min you would take 15, divide it by 60 (because it's minutes) and add that number to 30.

30deg + 15min

15min/60min = 0.25deg

0.25deg +30deg

30deg+15min=30.25deg

There are sixty minutes in an hour and sixty minutes in a degree. Does that make sense? If you convert it to a decimal number you can enter it into a calculator and continue the problem.

I hope this helps! ^_^

Hi Masoud and Special,

That was a good lesson that you just gave Masoud and it is stuff he needs to know but entering an angle into the calc can be much easier than that.

Make sure your calc is in degrees mode - there will be a little D at the toop of the screen.

now just press
20, degrees button, 30, degrees button (if you want to enter 25 seconds, then you press 25 degrees button again)
