From the shape we can clearly see that in case of NH3 the direction of vector is from H to N nd the direction of also the lone pair is same as H so this case dipole moment become vector sum is additive.
while in case of NF3 the direction of vector from N to F nd direction of lone pair is opposite to F so in this case vector sum is not additive so the dipole moment of NH3 is more than NF3
Hope it will helpful

❤.In NH3, the directionof the orbital dipole moment due to lone pair is in the same direction of the 'resultant dipolemoment' of the 3N-H bonds.
❤.Hence,the net dipole moment of NH3 is positive.
❤. But in NF3, molecule the direction of the orbital dipole moment due to lone pair is in the opposite direction to the 'resultant dipole moment'of the 3 N-F bonds.
❤.Hence, its net dipole moment decreases.
❤. Therefore,dipole moment of NH3 is greater than that of NF3
