Answer:
Octagon
Step-by-step explanation:
Sum of interior angles = 3*360 = 1080
sum of interior angles, is also, s = (n-2)180
From that,
n-2)180 = 1080
n-2 = 1080/180
n = 6 + 2
n = 8
Therefore, the figure is an 8 sided polygon or an octagon
22.86 metres
The two goal lines are 4.0 metres (13.1) from the end boards, and the blue lines are 22.86 metres (75.0 ft) from the end boards
-3x+4=-8
-3x=-8-4
-3x=-12
X=-12 divided by -3
X=4
X1=-5 and X2=9 that’s the answer
Answer:
B
Step-by-step explanation:
Clearly BD is shorter than AE so that is false.
BD is clearly on the opposite end of EC so it is not bisecting, as bisecting would be DE bisecting AC
AC has to be perpendicular to something to be a perpendicular bisector however it is a straight line.
