insa · Answer

i know how to do this but my answers are not correct

insa · Answer

i found out the line segments 
AB= 12.65
BC= 8.94
AC= 10

insa · Answer

my area= 69

insa · Answer

by the line segment formula

insa · Answer

okay but even if its 12 its still wrong

insa · Answer

okay the area is correct and maybe the line segment. how did u get area 48?

insa · Answer

well i dont have options.  the correct answers are
area=48
perimeter=32
perpendicular=9.6

insa · Answer

is BC=8? if yes, then how?

insa · Answer

okay
