Answer:
Because Douglas Adams said that it was the answer to life, the galaxy, the universe and everything in the Hitchhiker's Guide to the Galaxy, and it was just a joke, but now people are obsessed over it.
Step-by-step explanation:
You can find the value of x using the trigonometric function of cosine.
cos x = adj/hyp
cos 49 = x/55
55(cos 49) = x
36.083 = x
Hope I am right :)

Step-by-step explanation:
Any number greater than 1 will give a number greater than 2386
Answer:
(a.a)-(b.b)=|a|²-|b|²=0
As the dot product of the diagonals is 0, the diagonals must be perpendicular.
Step-by-step explanation:
- All the sides are equal in lengths and the sides that are opposite to each other and parallel so it can be expressed as the same vectors.
- These diagonals can be expressed by equation a+b and a-b
- Take the dot product of the diagonals and simplify.
(a+b).(a-b)=(a.a)-(b.b)
4. A vector dotted with itself is its length squared, and we know that the
side lengths are equal to each other.
(a.a)-(b.b)=|a|²-|b|²=0
