Question

Please jawab! nomor 37 dan 38!

Answer 1

37. a = 180 - 80 - 50 = 50
     b = 180 - 50 = 130
   c = b = 130
  d = a = 50
e = 180 - 80 = 100
f = 180 - 50 - 50 = 80
g = 180 - e = 180 - 100 = 80
h = 180 - 80 - 50 = 50

38.a. sudut alas = (180-30)/2 = 75
x = 180 - 75 = 105
b. sudut A = 180 - 80 - 80 = 20
sudut E = 180 - 20 - 30 = 130
x = 180 - 130 = 50
