Answer

# Explanation: ## Step1: Recall sine - function definition The sine of an angle $\theta$ in a right - triangle is defined as $\sin\theta=\frac{\text{opposite}}{\text{hypotenuse}}$. ## Step2: Identify angle and sides For $\angle B = 60^{\circ}$ in right - triangle $ABC$, the opposite side to $\angle B$ is $AC = 8\sqrt{3}$ and the hypotenuse $AB = 16$. ## Step3: Calculate $\sin60^{\circ}$ $\sin60^{\circ}=\frac{AC}{AB}=\frac{8\sqrt{3}}{16}=\frac{\sqrt{3}}{2}$. In the context of a trigonometric function $y = \sin(x)$, the input $x$ is the angle measure and the output $y$ is the sine value of that angle. So for $\sin60^{\circ}$, the input is $60^{\circ}$ and the output is $\frac{\sqrt{3}}{2}$. # Answer: input: $60^{\circ}$; output: $\frac{\sqrt{3}}{2}$
