1. measure angle c + measure angle b=180
   (Since opposite sides of a parallelogram)
   75 + d=180
   Therefore d=180-75
   Therefore d=105

2. Answer:

   105degree

   Step-by-step explanation:

   because adjacent angles m 180degree if we add them

   therefore

   75+x= 180

   x=180-75

   x=105

   so m angle b is 105degree
