MATLAB: Find the minimum value of x that corresponds to maximum value of theta

Question

Hello , I have :

x=30:0.5:300;
h=180;
hypot=sqrt(x.^2+h.^2);
phi=asind(h./hypot);
theta=90-phi;

Now , I want to find the minimum value of x that corresponds to maximum value of theta. How can I do this?

Thanks!
