Angles A and B are vertical angles.
If $m\mathrm{\angle }A=104\circ$ what is the $m\mathrm{\angle }B?$
$m\mathrm{\angle }B=\circ degrees$

Vertical angles are congruent. Therefore $m\mathrm{\angle }A=m\mathrm{\angle }B.$ If $m\mathrm{\angle }A=104\circ$, then $m\mathrm{\angle }B=104\circ m\mathrm{\angle }B=104\circ .$
