The answer to your question is sin 143°
Step-by-step explanation:
a) -sin 37 obtain the sin of 37° and change the sign of the result.
-sin 37 = -0.602
b) sin 143° just obtain the sing of 143
sin 143° = 0.602
c) sin 323° just obtain the sign of 323°. It is in the fourth quadrant where the sin is negative.
sin 323° = -0,602
d) sin (-143°) just obtain the sin of -143°
sin (-143°) = -0.602
- Conclusion
The second choice is the only different from the other choices.
