Angle D is 110 degree.Angle A and B has (5y+10).What is the value for y and the measures of angle C and angle A?

Answer 1

If A,B,C,D are the angles of a quadrilateral, then they add to 360. So,

(5y+10)+(5y+10)+C+110 = 360
10y+130+C = 360
10y+C = 230

Without some other information, I cannot uniquely identify y or C
