idk which is why i dont understand it
anonymous
  • anonymous
actualy, my bad, there is no solution i guess with the info you have
anonymous
  • anonymous
r u positive that it is a t?
anonymous
  • anonymous
no its like an angle thing with a line through it.
anonymous
  • anonymous
ahh thats means perpendicular i would think
anonymous
  • anonymous
maybe it means that this top angle is half of the bottom ones?
anonymous
  • anonymous
idk which is why im having trouble doing this problem
anonymous
  • anonymous
ive done that and i figured out the height which is six, but idk how to apply it to figure out the parameter

i think the answer is 40.32
anonymous
  • anonymous
any reason behind that?
anonymous
  • anonymous
SUROJ be nice
anonymous
  • anonymous
how'd you get 40.32?
anonymous
  • anonymous
|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

anonymous
  • anonymous
yes
anonymous
  • anonymous
okay let me try again lol
anonymous
  • anonymous
ok

72
anonymous
  • anonymous
thats the 2nd triangle
anonymous
  • anonymous

anonymous
  • anonymous
wait that is 42.8
anonymous
  • anonymous
