Be all safe!

I know i have asked many questions but is it correct?

2.1 for pi/6 and 10.5 for 5pi/6

Do i divide 5pi/6 by 4? And thanks for the help! :)

What about the others are they correct??

Coterminal angles are angles in standard position that have the same terminal side.

To find an angle in standard position that is coterminal with -6pi/5

We add or subtract multiples of 2pi

The first addition gives,

-6pi/5+2pi=4pi/5

yes it is correct
