theta = 0:1:90;
3010 == Xo + (V .* cosd(theta)) .* t
I'm trying to calculate the angle needed to travel 3010 ft but I keep getting this error message
Arrays have incompatible sizes for this operation.
Error in lab2 (line 30)
3010 == Xo + (V .* cosd(z)) .* t

Ran in:
Xo = 1234;
V = 20000;
syms theta
t = .1:.1:1;
eqn = 3010 == Xo + (V .* cosd(theta)) .* t
eqn = 
thetas = double(arrayfun(@(E) vpasolve(E), eqn));
plot(t, thetas)
