Step-by-step explanation:
The total number of wrestlers are 6 and each have to wrestle each other wrestler only once.
It means, the first wrestler have 5 opponent, second have 4 opponents , third have three oponenets , fourth have two opponents and the fifth have only one opponent.

4x+19=7x+16
4x=7x-3
-3x=3
x=1
Angle AOD and < BOD are supplementary since they are both right angles which equal 180°.
<h3>What is a supplementary angle?</h3>
It should be noted that a supplementary angle simply means an angle that adds up to 180°.
In this case, the angles given are both rights angles. This will be:
= 90° + 90°
= 180°
In this case, Angle AOD and < BOD are supplementary since they are both rights angles which equal 180°.
