The circumcenter is where the perpendicular bisectors meet.
if you sketch the triangle, you will see that it is a right triangle, with the right angle vertex at (2,1)
one perpendicular bisector is x=1, another perpendicular bisector is y=3
they meet at (1,3)
so (1,3) is the answer.
10+15+20+25+30+35+40+45+50+55+60+65=450
There are 450 seats in the auditorium
*pst* Put as most brainliest
The answer to the first question is b
I don’t know the answer to the second one sorry
(0,0)(1/3,7/3)
slope = (7/3 - 0) / (1/3 - 0) = (7/3) / (1/3) = 7/3 * 3 = 21/3 = 7 <==
Four times fifteen plus twenty in parentheses
idk if its correct though <span />
