Thank you allot. Please answer one the three questions as I think it is your policy. thanks again!

3. The exact value of sin 285 is Lesson - V3 -1 A. 212 -V3+ 1 B. 212 C. V3 - 1 212 D. V3+ 1 212 Hint: The exact value of sin 285. can be determined using an identity such as a sum or difference identity. The values used to make the sum or difference should be chosen to capitalize on special ratios and angles. Numerical Response 2. To verify the identity 1 - sin 0 cos 0 tan 0 = cos20, a student substituted 0 = 328 . To the nearest hundredth, the value of each side of the identity was Hint: Technology may be used. 4. The expression sin (A + it) - cos (A + it) can be simplified to A. sin A - cos A sin A + cos A COSA - sin A D. - sin A - cos A Hint: Use an identity. jeairmag-non feepiel ord , Obs "0 nigmob ort nevin al J - O'nia = (09es - 0ni)9 me vitnobl arti noteorpob Illw dose , Move eA. .0 not coulsy eldiaelmmeg-ron evert
