% Given vectors
A = [5, 3, 1];
B = [-1, 2, 0];

% Magnitudes
mag_A = norm(A);
mag_B = norm(B);

% Dot products of A and B
dot_AB = dot(A, B);


%Cosine
cos_theta = dot_AB/(mag_A*mag_B);

%Angle in degree
theta = acosd(cos_theta);

%Result
fprintf('The angle between vectors A and B is %.2f degrees\n', theta);
