Question: A photon with wavelength 0.1385nm scatters from an electron that is initially at rest.

Part A: What must be the angle between the direction of propagation of the incident and scattered photons if the speed of the electron immediately after the collision is 8.90 × 106 m/s?

I know the correct answer but explain how to get this answer!
