that a 30, 60, 90 triangle
anonymous

me too
anonymous
  • anonymous
ya know how 30, 60, 90 triangles the sides are 3,4,5
anonymous
  • anonymous
Yeah
anonymous
  • anonymous
so i divided 45 by 5 and got 9
anonymous
  • anonymous
do u see why?
anonymous
  • anonymous
I see how you got 45 / 5 = 9 but then how does it turn to 26ft
anonymous
  • anonymous
cause u multiply 9x3=27
anonymous
  • anonymous
but obviously its not gonna be exact so i rounded it down to 26
anonymous
  • anonymous
ya gotta know hot to cheat math sometimes lol
anonymous
  • anonymous
Lol, aight thanks!
anonymous
  • anonymous
u got it?
anonymous
  • anonymous
oh wait, so when you did 9 x 3, wouldn't it have been 9 x 4 since its on the 60 degree angle side
anonymous
  • anonymous
no because the side x is opposite the angle 30
anonymous
  • anonymous
Ohhhhhh I see, aight I got it now, thanks bro
anonymous
  • anonymous
tell me if its right
anonymous
