Answer:
266
Step-by-step explanation:
So the diagonal of cube
this was a practice act question so her's the answer
look at the cube through one of the faces
you will see the diagonal as the hypotonuse of a triangle
and also a triangle on the floor (look at attachment)
the ,diagonal is 28
a^2+b^2=28^2
a=b since it is a cube
remember that this is a 45,45 triangle so therefor
a=b=x
c=x√2 so
28=x√2
divide both sides by √2
28/(√2)=x
the diagonal on the floor is 28/(√2)
the sides of the triangle form another 45 45 90 triangle with 28/(√2) as hyponuse so
a=b=x
c=x√2=28/(√2)
solve for x
x√2=28/(√2)
divide both sides by √2
same as mujlitply both sides by 1/(√2) so
28/(√2) times 1/(√2)=28/(2)=14
the answer of 1 diagonal is 14 cm
the answer is 14cm
ummmmmmmmmmmmmmmmmmmmmmmmmm?mmmmmmmmmmmmmmmm?mmmmmmmmmmmmm withhhhhhhhhhhhhhhhh whatttttttttttttttttt
I hope this helps you
slope=m
(-3,4) x'=-3 y'=4
(4,-1) x"=4 y"=-1
slope formula :
m. (x'-x")=y'-y"
m. (-3-4)=4-(-1)
m.-7=4+1
m=-5/7
In maths, Distance is described as the quantity of space between two points, and further calculation can be defined as follows:
