\(\displaystyle\beta={120}\). There are 3 bonds and no unshared pairs, so itsgeometry is trigonal

\(\displaystyle\delta={104.5}\) There are 3 bonds and one unshared pair,resulting in a "squished" tetrahedral geometry

\(\displaystyle\epsilon={120}\) Another trigonal geometry

\(\displaystyle\phi={109.5}\) This is a standard tetrahedral geometry,occurring when carbon bonds to 4 atoms

\(\displaystyle\gamma={120.3}\) 3 bonded atoms with no unshared pairs

Bonds X and W are the same length because of resonance. Electrons are shared equally among the 6 carbons in the ring.

Bond X is longer than bond Z because because bond Z is a doublebond, while X is closer to a 1.5 bond. Higher bond orderspull the atoms closer together.

Bond Y is longer than bond Z for essentially the same reason as above.
