Answer:
see explanation
Step-by-step explanation:
Co terminal angles are angle ± 2π, that is
[tex]\frac{11\pi }{8}[/tex] + 2π
= [tex]\frac{11\pi }{8}[/tex] + [tex]\frac{16\pi }{8}[/tex] = [tex]\frac{27\pi }{8}[/tex]
and
[tex]\frac{11\pi }{8}[/tex] - 2π
= [tex]\frac{11\pi }{8}[/tex] - [tex]\frac{16\pi }{8}[/tex] = - [tex]\frac{5\pi }{8}[/tex]
