You can write it in two types of fractions:
1) ur answer will be 26 and 2/10 which can be simplified to 26 and 1/5
2) ur answer will be 262/10 which can be simplified to 131/5
The first is the more recommended way of writing your answers.
The formula for interior angle sum is 180(n - 2).
Backtrack it from that.
180(n - 2) = 1980.
1980 / 180 = 11 = n - 2.
11 + 2 = 13 = n.
The polygon has 13 sides.
I believe the answer is t=1.
