Answer:

223° and 317°

Explanation:

To find the values of x for which sin x = -0.6745, we can use the inverse sine function (sin^-1) on a calculator:

sin^-1 (-0.6745) = -43.01° or -136.99° (rounded to two decimal places)

However, since the question specifies that x is in the interval 0° < x < 360°, we need to adjust our answer to fit within that range.

For the first solution, we can add 360° to get:

-43.01° + 360° = 316.99°

Therefore, one solution is x = 317° (rounded to the nearest degree).

For the second solution, we can subtract from 360° to get:

360° - 136.99° = 223.01°

Therefore, another solution is x = 223° (rounded to the nearest degree).

Thus, the values of x for which sin x = -0.6745 within the interval 0° < x < 360° are approximately 223° and 317°.
