For problem b, why is it not less than 120 degrees instead of 120 degrees for the atoms in the trigonal plane? I thought that because there is a lone pair, the Cl-Te-Cl bond angle would be less than 120 degrees?

Since TeCl4 is see-saw shaped, I think that the angles are less than the ideal angles of 90 and 120 degrees. You're right that the lone pair will cause repulsion and distort the actual bond angles.

For 2E.15 b I think TeCl4 is actually seesaw shaped not trigonal planar so it should have bond angles of approximately 90 and 120 degrees

TeCl4 is See-saw shaped so the bond angles have to be 120 and 90.
