%% Question 1 - Step 1
CBT = [cos(24) -sin(24) 0 779 ; sin(24) cos(24) 0 599 ; 0 0 1 0 ; 0 0 0 1] % The definition of frame {C} in {B}
CP = [100 ; 100 ; 0 ; 1]; % Given position
BP = CBT*CP % Position of P in frame {B}

I understood the problem. When calculating on MATLAB, the angles are in radians, so I need to convert to degree.

Have you checked that both are using degrees, or both radians? The Matlab as you've written it is using radians (use sind(24) and cosd(24) if the 24 is in degrees).

+1. And it would be rather surprising to me if one truly intended to compute the sin(24), where the 24 was in RADIANS. 24 radians is a relatively large number of radians, and an integer stongly suggests degrees were intended.
