how would you find the reference angle for -175 degrees?

Question

amistre64 · Answer

-175 is almost to the 180 mark; |180-175|

anonymous · Answer

ok. thank you! so would you use absolute value for all of these proble,s?

amistre64 · Answer

you dont have to, but it doesnt hurt.  the ref ang will be a positive value; so just in case you subtract the wrong way it corrects itself

anonymous · Answer

i think no... -175º is the same as 185º isn't it?
360-175=185

anonymous · Answer

and say if i was given sin 150, how would i find the reference angle as that? would it be sin 30?

amistre64 · Answer

-175 or 175; doesnt matter a hill of beans; theyare each 5 away from 180

amistre64 · Answer

it would be 30 yes
