Answer 1

170 degrees is not a common angle on the unit circle...
you sure it's 170 degrees?

Answer 2

yep.

Answer 3

ok... we might have to use identities then...

Answer 4

but I do not know much about trig identities, plus trig ids are later on in my textbook.

Answer 5

if I give you the answer, might that help you solve the problem?

Answer 6

yes..

Answer 7

0.174

Answer 8

that's a calculator answer... does it give you an exact answer?

Answer 9

It is the answer given in my text.

Answer 10

ok... that is a calculator answer and sin(170) can't be determined by the unit circle.
look at the instructions in your textbook for this problem... what does it say?

Answer 11

it gives no instructions.

Answer 12

really? they should at least have some instructions for a group of problems...

Answer 13

so sin(170) can't be determined with the unit circle... if it can be, i don't know how... sorry... :(

Answer 14

thank you for trying.

Answer 15

yw...
