Answer :
SOLUTION
A coterminal angle is an angle that points to an exact direction like the original angle.
Since a complete circle is 360 degrees.
The positive coterminal angle will be
[tex]360^0+166^0=526^0[/tex]Hence the positive coterminal angle is 526°
Then the negative coterminal angle will be
[tex]166^0-360^0=-194^0[/tex]hence the negative coterminal angle will be -194°
The positive and negative coterminal angle to 166° are 526°, -194°
Therefore the right option is 1(A)
