Abcd is a quadrilateral
=angle A + Angle B + angle C + angle D= 360 degree
=angle C =110 degree angle D =80 degree
=angle f + Angle e and Angle a + angle b is equal to 180 degrees (straight angle)
= PQ BC is also quadrilateral
= so angle e is equals to 110 degree and Angle b is equals to 80 degree
=apdq also quadrilateral
=angle f is equal to 80 degree and Angle a is equals to 110 degree
=angle A + Angle B + angle C + angle D= 360 degree
=angle C =110 degree angle D =80 degree
