A school principal is mapping out some new features for a triangular playground, He sketches the playground on grid paper. The coordinates of the vertices of the
playground are (1, 10). (-5, 2), and (7,2),
The principal wants to plant a tree at the circumcenter of the playground, What
are the coordinates of the tree?

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

stop cheating
