As a hint:
That will suffice. Why not try it?
Or, you could find the inclination of each line, best done using atan2. Then subtract. That too will work, as long as you are careful.

x = [800 905]; % common point
y = [250 330];
a = [800 905]; % common point
b = [825 333];
angle_between = (atan((y(2)-y(1))/(x(2)-x(1)))...
- atan((b(2)-b(1))/(a(2)-a(1)))) * 180/pi % in degrees
