1. Answer:

   3x-8+2x+13 = 180

   3x+2x-8+13 = 180

   5x+5 = 130

   5x = 125

   x = 25

   A = 3x-8

   = 3 x 25 – 8

   = 75-8

   therefore A = 67°

   D = 2x + 13

   = 2 x 25 + 13

   = 50 + 13

   = 63

   therefore D = 63°

   therefore the angles are 67°,63°,67°,63°.

2. Answer:

   x=37

   Step-by-step explanation:

   here A+D=180

   and A=C,

   B=D. because it’s parallelogram
