yes, angle is 45 degree.
the force in a member must act along direction of member.
since FD = DE = 2m, therefore FE is inclined at angle 45 degree.
in fact, as all the vertical and horizontal members are 2 m length, therefore all the diagonal members are incline at angle 45 degree.
suggestion ... before proceeding to work out force in members, should work out the reaction forces at A and D first.
