Since the point lies on the unit circle, it satisfies

x^2+\left(-\dfrac8{17}\right)^2=x^2+\left(\dfrac8{17}\right)^2=1

Solving for x gives two possible solutions:

x^2=1-\left(\dfrac8{17}\right)^2
x=\pm\sqrt{1-\left(\dfrac8{17}\right)^2}

Given that x is in quadrant IV, you know that its value must be positive, so

x=\sqrt{1-\left(\dfrac8{17}\right)^2}=\sqrt{\dfrac{225}{289}}
