Hello I need help on my Quiz 2.4 (Question 3-4 and numerical response 2)

Quiz 2.4 - TS Mathematics 30-1 3. The exact value of sin 285 is -13 - 1 A. 212 -13+1 B. 212 V3 -1 C. 212 V3 + 1 D. 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 = cos' 0, 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 B. sin A + cos A C . cos A - sin A D. - sin A - cos A Hint: Use an identity
