b = 180 - 58 = 122
answer: 122°
c = 180 - 82 = 98
answer: 98°
d = 180 - 60 = 120
answer: 120°
e = 180 - 37 = 143
answer: 143°
f = 180 - 24 = 156
answer: 156°
then for x and a,
the sum of the internal angles of a 6 sided polygon is
[tex](n-2)(180)=(6-2)\times180=4\times180=720[/tex]
therefore:
[tex]a=720-122-98-120-143-156=81[/tex]
answer: a = 81°
x = 180 - 81 = 99
answer: 99°
