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
Nothing ;) Bc i don’t know hahahaha banana
The answer is A (x+5)(x+3)
explanation:
the GCF of 15 is 3 and 5
3 and 5 also add up to 8 making each of the number the zeros
(x+5)(x+3)
Answer:
21
Step-by-step explanation:
3x+6=5x-4 because of alternate interior angles of a parallel line
10=2x
x=5
15+6=21
okay I found out that the answer is 2
