  • A 44.5\(^o\) , 224.5\(^o\)
  • B 123.5\(^o\) , 190.5\(^o\)
  • C 135.5\(^o\) , 213.5\(^o\)
  • D 135.5\(^o\) , 224.5\(^o\)
Correct Answer: Option D
Explanation:
cos x = -0.7133
x = cos \(^{-1}\)(0.7133)
= 44.496\(^o\)
x = 180 - 44.495\(^o\)
x = 135.5\(^o\)
and x = 180\(^o\) + 44.495\(^o\)
= 224.5\(^o\)
