A quadrilateral has two angles that measure 60° and 100°. The other two angles are in a ratio of 9:11. What are the measures of those two angles?

Math, microeconomics or criminal justice
9/11 = x/(200-x)
1800-9x = 11x
20x = 1800
x = 1800/20 = 90 degrees
200-x = 110 degrees
90 and 110 are the other two angles
