44x + 55x + 77x = 6,464 centimeters.
x =

OR maybe that's another of those infamous Brainly typos.
4x + 5x + 7x = 64 centimeters.
x = 8
Therefore the sides are
4*8 = 32
5*8 = 40 and
7*8 = 56 centimeters
⟨0,1⟩ could be taken to begin at the origin and end at (0,1). <span> ⟨0,1⟩ has the length/magnitude of 1 and direction j. So the desired unit vector is simply j.</span>
