Population, because the more people there are in a town, the more mailboxes and traffic lights there will be. There will have to be more in order to supply the population.
Answer:
You can find 0.5% of a number by multiplying the number by
Step-by-step explanation:
Answer:
Hypotenuse-Leg Theorem (HL)
Step-by-step explanation:
The HL theorem states that two right triangles are congruent if their hypotenuses are the same length and one leg is the same length. Since the diagram shows this, you can say these triangles through the HL theorem.
Answer:
100
Step-by-step explanation:
In a 45-45-90 triangle, the hypotenuse is always larger than either of the legs by a factor of 
. x is therefore:
Hope this helps!
Arcsin x + arcsin 2x = π/3
arcsin 2x = π/3 - arcsin x
sin[arcsin 2x] = sin[π/3 - arcsin x] (remember the left side is like sin(a-b)
2x = sinπ/3 cos(arcsin x)-cosπ/3 sin(arc sinx)
2x = √3/2 . cos(arcsin x) - (1/2)x)
but cos(arcsin x) = √(1-x²)===>2x = √3/2 .√(1-x²) - (1/2)x)
Reduce to same denominator:
(4x) = √3 .√(1-x²) - (x)===>5x = √3 .√(1-x²)
Square both sides==> 25x²=3(1-x²)
28 x² = 3 & x² = 3/28 & x =√(3/28)
