Hey there! :D

All angles in a triangle equal 180 degrees. An exterior angle is supplementary to the interior angle next to it. (also equal to 180 degrees)

92+24+<B= 180

116+<B= 180

Subtract 116 on both sides.

<B= 64

So,

180-64= 116

The exterior angle of <B is equal to 116 degrees.

I hope this helps!
