ok?
myko that comes out to not an option
it comes out to 42
this one is a tricky one let me try again
|dw:1332542529410:dw| what this means?
yeah that is throwing us off
idk which is why i dont understand it
actualy, my bad, there is no solution i guess with the info you have
r u positive that it is a t?
no its like an angle thing with a line through it.
ahh thats means perpendicular i would think
maybe it means that this top angle is half of the bottom ones?
idk which is why im having trouble doing this problem
ive done that and i figured out the height which is six, but idk how to apply it to figure out the parameter
|dw:1332543779552:dw|
i think the answer is 40.32
any reason behind that?
SUROJ be nice
how'd you get 40.32?
|dw:1332543858044:dw| well i tried to find the height which is 12 using the h=root3*s/2 formula, then i cut the triangle in half, then applied the A^2+B^2=C^2 to find one of the sides which is 13.89 then added all of them together which is 2*13.89+14 which is 41.78 so it could be 40.32 lol
oh ok:)
i could be wrong tho D:
:/
is that equilateral triangle?
yeah it should be
i dont think so
no its not cuz only two sides are the same
or an isolyze triangle ?
its an isosceles triangle
yes
okay let me try again lol
ok
|dw:1332545361479:dw|
72
thats the 2nd triangle
so the perimeter of def is 72?
wait that is 42.8
yea the perimeter
sorry 45.8
