Degrees, minutes and seconds are denoted by the symbols °, ', ". e.g. 10° 33' 19" means an angle of 10 degrees, 33 minutes and 19 seconds . A degree is divided into 60 minutes (of arc), and each minute is divided into 60 seconds (of arc).
A prime is a symbol similar to an apostrophe or a close quotation mark that in technical usage follows a number to denote a unit; in lay content, a single prime (′) most frequently represents feet or minutes, and a double prime (″) indicates inches or seconds (“The deck is 10′ 6″ by 12′”) or minutes (“The duration was
The book states that to be more precise, a degree is divided up into sixty equal parts called minutes, and that each minute is divided into sixty equal parts called seconds. This makes sense since we already know that there are sixty seconds in a minute.

Divide the number of minutes by 60 and add to the number of degrees. So, for example, 12° 28' is 12 + 28/60 which equals 12.467°. Next multiply by π and divide by 180 to get the angle in radians. 2.
Entering angles in DMS measure
- Enter the number of degrees and press [2nd][APPS][1] to insert the degree symbol.
- Enter the number of minutes and press [2nd][APPS][2] to insert the symbol for minutes.
- Enter the number of seconds and press [ALPHA][+] to insert the symbol for seconds.
Angles can be divided just like ordinary numbers. An angle can only be divided by a ray on the interior of the angle, though. Such a ray that divides an angle into two equal angles is called an angle bisector.
One of the issues is how to round off time values from seconds to minutes or minutes to hours. You can use the MROUND function to round off time values. The MROUND function returns a number rounded to the nearest instance of a specified multiple. Start by formatting numbers to the time format.
Approximating 6.75 to the nearest whole number gives 7. Going by the rule, 45 minutes will be approximated to 1 hour.
Round time to nearest 15 minuteSelect a cell and type this formula =ROUND(A2*(24*60/15),0)/(24*60/15) into it, and press Enter key, then drag autofill handle to the cells you need.
Rounded to nearest degree means we have to round the final answer in the nearest degree. Let us suppose if the answer is 42.7 degrees then the final answer after rounded to nearest degree is 43 degrees.
Here's the general rule for rounding:
- If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up. Example: 38 rounded to the nearest ten is 40.
- If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down. Example: 33 rounded to the nearest ten is 30.
You just have to leave the first two numbers before the point. :) If a number is bigger after the point like for example 10.59 the answer would be 11 because it can be rounded by the 5. :) soobee72pl and 4 more users found this answer helpful.
Rule: When the calculated sample size is not a whole number, it should be rounded up to the next higher whole number.
