1. Answer:

   a=140,

   b=90,

   c=35

   ,d=95

   Step-by-step explanation:

   A+B+C+D=360

   A+C=180

   B+D=180 SINCE ABCD IS A QUADRILATERAL

   G.T. C-D=60 & A-C-D=10 & B=90

   ANGLE D=180-ANGLE B 180-90=90

   ALSO GIVEN, ANGLE C- ANGLE D=60

   ANGLE C =60 + ANGLE D =60+90=150

   SINCE ABCD IS A QUADRILATERAL, ANGLE A+ ANGLE C=180

   SO ANGLE A =180-ANGLE C=180-150=30

   ANGLE A=30 DEGREES

   ANGLE C=150 DEGREES

   ANGLE D=90 DEGREES
