Answer:
one side = 
Step-by-step explanation:
if you draw an octagon on a piece of paper, you can draw a square around it, you should be able to see a diagram of this attached, ignore the 6.
Let's say TP = a
since it's a regular octagon, TP = HT
and using the Pythagoras Theorem, we know a² + b² = c² and thus:
√(AT² + HA²) = HT
and since AT = HA which we will call x, the equation becomes:
√(2x²) = HT = a
rearrange the equation to solve for x and you get:
2x² = a²
x² = 
x = 
which, if you rationalise the denominator, you get:
x =

Answer:
$325,120.00
Step-by-step explanation:
This is my first answer so hopefully I do this correctly. In essence it's exactly the same as number 22!
The realtor earns $10,566.40 off of a comission of 3.25%. A comission is pretty much just a cut of however much the house cost; which a realtor gets for helping to sell the property. So we could say that the comission is equal to 3.25% of however much the house cost.
Say the house price = $x, so our equation would be:
$10,566.40 = (3.25%)•($x) or
10,566.40 = (.0325)•($x)
By solving for x we get:
$x = (10,566.40)÷(.0325) = $325,120
Answer:
x=4
Step-by-step explanation:
since triangles are proportional by 2:1, then:
16/2=3x-4
8=3x-4
3x=12
x=4
