    I can only assume you mean \sin{(x - 10)} = 0. Inverse sine of 0 is equal to 0, and you should know that at \pi and 2\pi the sine function is equal to zero. so x = 10, \pi + 10 and 2\pi + 10

    You may need your answers in the range 0 \leq x \leq 2\pi which can be done by subtracting multiples of 2\pi from the above answers.
