The judges at the track meet will award prizes to the top 4 teams. How many different ways can the top four teams place??

Nata [24]

They could give to teams more than likely on an average score the whole team has done, or at least that is what they are supposed to do. but they also might award the team which had more teammates get better places. for example if party place got three people on their team but they all did 3rd then boring barn who got 1 person could possibly win if that one person gets 1st place.

BD is the angle bisector of ZABC.

mojhsa [17]

Answer:

B:25°

Step-by-step explanation:

Now $\angle ABC$ gets bisected by $BD$ .

$\angle ABD=25^{\circ}$

Since, the angle is bisected, this means that the angle is split into two equal parts or the angle is halved.

We know that one of the angles is $25^{\circ}$ so the other angle has to be $25^{\circ}$ also.

Hence, the $m\angle DBC=25^{\circ}$ .
