al=60; be=45; b=2;(a-b)/(a+b))=tand(0.5*(al-be))/(tand(0.5*(al+be)))Guys how can i find 'a' variable with solve command? its 0.3371 but i didnt find this result
Thank you

The cosd function does not exist in the Symbolic Math Toolbox.
Try this:
syms a bb_solved = solve((350+1-((a*0.984807753012208)+(b*cos(asin(((a*0.173648177666930))/b))))),b);More solutions than you can shake a stick at.
syms b m thetam = 5;theta = 20;eqn = tand(theta)==(2*(1/tand(b)))*(((m*m*(sind(b)*sind(b))-1))/(m*m*(1.4+(cosd(b)*cosd(b)))+2)) ;sol = solve(eqn, b, 'returnconditions', true)sol.b
sol.parameters
sol.conditions
k = 0;z1 = solve(subs(sol.conditions, sol.parameters(1), k));sol6_0 = simplify(subs(subs(sol.b, sol.parameters(1), k), sol.parameters(2), z1))
vpa(sol6_0)
k = 1;z1 = solve(subs(sol.conditions, sol.parameters(1), k));sol6_1 = simplify(subs(subs(sol.b, sol.parameters(1), k), sol.parameters(2), z1))
vpa(sol6_1)
k = -1;z1 = solve(subs(sol.conditions, sol.parameters(1), k));sol6_m1 = simplify(subs(subs(sol.b, sol.parameters(1), k), sol.parameters(2), z1))
vpa(sol6_m1)
