Are you allowed to use a calculator? Do you need an exact value?
In the latter case, you might use angle-sum identities or half-angle identities to find the two sines separately, or maybe something you've been taught provides a way to find the sum directly. (I don't see any offhand.)
Without knowing anything about your context, I have no idea what help might be appropriate.
