Which of the following is not equal to the other values?

-sin37°
sin143°
sin323°
sin(-143°)

Choice B is correct.

All of the others have a refined decimal of approximately -0.601.

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.

37
