    If the problem is referring to the angle in a regular nonagon, we can solve it using the formula 180 (n-2) where "n" is for the number of sides. We know that number of sides of the regular polygon is 9. Hence, we can solve the problem and the solution is shown below:

    degree = 180 (9-2)

    degree = 1,260°

    The answer is the letter "C" which is 1,260°.
