Work out the size of one of the exterior angles

hodyreva [135]

Given Information :-

⠀

A polygon with 10 sides ( Decagon )

⠀

To Find :-

⠀

The value of one of the exterior angles

⠀

Formula Used :-

⠀

$\qquad \diamond \: \underline{ \boxed{ \pink{ \sf Exterior ~angle = \dfrac {360^\circ}{no. ~of~sides}}}} \: \star$

⠀

Solution :-

⠀

Putting the given values, we get,

⠀

$\sf \dashrightarrow Exterior ~angle = \dfrac{360 ^\circ}{10} \: \: \\ \\ \\ \sf \dashrightarrow Exterior ~angle = \frac{36 \cancel{0}^\circ}{ \cancel{10}} \: \: \\ \\ \\ \sf \dashrightarrow Exterior ~angle = \underline{ \boxed{ \frak{ \red{36^\circ}}}} \: \star \\ \\$

Thus, the value of the exterior angles of a Decagon is 36°.

⠀

$\underline{ \rule{227pt}{2pt}} \\ \\$

How do you factor quadratics by grouping

Kaylis [27]

Here's an example Its also call the 'ac' method:-

factor 2x^2 - 13x - 15

Multiply first coefficient by last number which is 2*-15 = -30

Now we need 2 factors of -30 which will when added give - 13:-

-15 and 2 looks good. So we can write:-

2x^2 - 13 x - 15

= 2x^2 + 2x - 15x - 15

factor by grouping first 2 and last 2 terms , we get:-

= 2x(x + 1) - 15(x + 1)

the x+1 is common so we have:-

(2x - 15)(x + 1) Answer

Hope this helps.

miskamm [114]

Answer:

The probability is 28 % ( approx )

Step-by-step explanation:

Since, there are only two possible outcomes in every trails ( residents are in their forties or not ),

So, this is a binomial distribution,

Binomial distribution formula,

Probability of success in x trials,

$P(x)=^nC_x p^x q^{n-x}$
