WILL GIVE BRAINLIST

B.150°

Step-by-step explanation:

A regular hexagon has six sides.

The measure of the interior angle is 120°

At the point where vertices B and E share a common edge, angle BED is 90°

The sum of angle measures at point of intersection of edge BE ,ED and FE is equal to 360°

To get measure of angle DEF will be ;

=360° - {90°+120°}

=360°- {210°}

=150°
