Find the measures of two angles, one positive and one negative, that are coterminal with pi divided by ten.

OpenStudy (dumbcow):

simply add and subtract 2pi to pi/10

OpenStudy (anonymous):

I learned that but wouldn't it just be 2pi/10? 2pi/10 isn't a anwser choice so I'm confused.

OpenStudy (dumbcow):

2pi + pi/10 = 20pi/10 + pi/10 = 21pi/10

OpenStudy (anonymous):

So you would multiply 2 to 10 to get 20 and then add pi?

OpenStudy (dumbcow):

yeah its simply adding fractions by getting common denominator

Oh okay. Thank you!
