<span><span>If you would like
to </span>divide 42 in the ratio of 1 : 2 : 3, you can do this using the following
two steps:<span>
<span>First, add the numbers: </span>1 + 2 + 3 = 6
<span>Second, divide and multiply: 1</span> / 6 * 42 = 7
2 / 6 * 42 = 14
3 / 6 * 42 = 21
<span>The result you are looking for is </span>7 : 14 : 21<span>.</span></span></span>
The sum of all of the exterior angles of any regular polygon is 360 (I'm assuming by decagon you mean a regular dodecagon).
Because the total has to be 360, and a decagon has 10 sides, you divide 360 by 10 to get each exterior angle.
360 ÷ 10 = 36, so each exterior angle of a decagon is 36 degrees.
