Answer
$$-\sin35^\circ=\sin(-35^\circ)$$
20 goes with A.
Work Step by Step
$$-\sin35^\circ$$
Recall the negative-angle identities for sines:
$$\sin(-\theta)=-\sin\theta$$
Therefore, we can rewrite $-\sin35^\circ$ as follows:
$$-\sin35^\circ=\sin(-35^\circ)$$
Looking at the choices, we see that 20 is matched with A.
