It keeps giving “unrecognized function or variable ‘theta’

Perhaps:
syms theta
just after the ‘outputs’ comment would help.
Also MATLAB is case-sensitive, so change:
Angle = 10;
to:
angle = 10;
.

if theta is symbolic and angle is numeric then assignment to
Eq340(theta, angle)
would be an error.
I say that you should
syms theta angle
and change the Angle in Eq340 to angle
After that the last statement would become
theta = subs(S, angle, Angle)
Question: are you sure that you want to be working with 10 radians? It looks to me more likely that you should be using sind(angle) instead of sin(angle)
