The formula for number of sides a polygon has given the sum of its internal angles is 1800 * (n - 2). So, for a triangle, n=3, and sum of the angles is 1800.
So to answer your question, first divide 1,980 by 180 to get 11. Now add 2, and you get the number of sides, 13.
In case you're curious, a 13 sided polygon is called a triskaidecagon.
