First you write down the number of sides that it has.
Let "n" represent the number of sides.
So you have a hexagon which of course is 6 sides.
The next step is to find the SUM of Interior Angles which is (n-2) x 180
So 6 - 2 is 4 and x 180 = 720
The last step is to divide by the original number of sides the polygon has. So since a hexagon has 6 sides, you'd do 720 / 6 =120
Your answer is 120
Both 9/3 and 54/18 come out to 3, so your answer is:
18:54
Answer:
-8x
Step-by-step explanation:
First, we are going to add

from both sides of the equation:


Next, we are going to use the trig identity:

to rewrite our expression:



Finally, using our unitary circle, we can infer that

from 0 to

when

and

We can conclude that the solutions of the equation <span>cos (x) tan (x) -1/2=0 over the interval [0,2π] are: </span>
Answer:
$540.98
Step-by-step explanation:
future value= $ 50,000
number of deposits (n)= 8*12 = 96
rate (r) = 4% per month
= 4÷12 per annum
= 0.33% p.a
i = 0.33÷100
= 0.0033
We know,
Future value of annuity = P÷i [ (1 + i)^n - 1 ]
$50,000 = P÷ 0.0033 [ ( 1+0.0033)^96 - 1]
$50,000 * 0.0033=P [ (1.0033)^96 - 1 ]
$165 = P*0.305
P = $165÷0.305
P = $ 540.98
Rough::
let x= 1.0033)^96
log x = 96 * log (1.0033)
log x = 0.1156
x = Antilog (0.1156)
= 1.305
1.305 - 1 = 0.305
