The sum of the measures of the angles in any polygon can be found using the formula: (n-2)*180 degrees, where n is the number of sides of the polygon.
In this case, a nonagon has 9 sides, so the sum of the measures of the angles in a nonagon is (9-2)*180 = 7*180 = 1260 degrees.
Therefore, the correct answer is A) 1260 degrees.
