In triangle abc angle "a" equals 92° and "c" equals 24°. whats the exterior angle of "b"?

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!
