Answer:

A = C = 110

B = D = 70

sum of angles of triangles ABC is 180 so if you add all the variables they will be 18x and this means 18x = 180 and x = 10

so angle B is 70 degree and it's opposite angle D is 70 degree because opposite angles are equal in parallelogram

angle A is 50 degree + 60 degree because alterbati6a angles are equal in parallelogram

Answer:

A=C =110

B=D =70
