Two angles of a quadrilateral measure 250° and 40°. The other two angles are in a ratio of 5:9. What are the measures of those two angles?

Need ! give step by step solutions on how to solve number one [tex]\frac{9-2\sqrt{3} }{12+\sqrt{3} }[/tex] number two [tex]x+4=\sqrt{13x-20}[/tex] number three (domain and range) [tex]f(x)=2\sqrt[3]{x} +1[/tex]

The equation x2 – 1x – 90 = 0 has solutions {a, b}. what is a + b?

Need 50 will mark brainliest answer. find the lengths of all the sides and the measures of the angles.
