The zero of a function is any replacement for the variable that will produce an answer of zero. Graphically, the real zero of a function is where the graph of the function crosses the x‐axis; that is, the real zero of a function is the x‐intercept(s) of the graph of the function.
According to the basic trigonometric equation for right angle triangles: Sin(x) = opp/hyp so... Sin(60) = 4(sqrt(3))/x x = 4(sqrt(3))/sin(60) x = 6.928.../0.866... x = 8
