    This is the the concept of trigonometry, to get the sine value of the the function given we shall proceed as follows;

    Using Pythagorean theorem, the hypotenuse of the triangle will be found as follows;

    The side length will be 8 units since the y-coordinate is - 8

    The side width will be 3 units since the x - coordinate is 3

    c^2=a^2+b^2

    c^2 = (3) ^2 + (-8) ^2

    c^2=9+64

    c^2=73

    c=sqrt (73)

    Therefore the sine value will be:

    sin x=3/sqrt (73)

    multiply both numerator and denominator by sqrt (73) we get:

    sin x = (3√73) / 73

    Therefore the answer is A]
