The sum of the angles in a pentagon is 540°.
This means that each angle is 108°.
Inside you pentagon, a triangle is drawn. This triangle is isosceles, because the corners are on the points of the regular pentagon. You know that angle C is 108°.
Angles in a triangle add up to 180°.
B and D will be the same size as this is isosceles.
180°-108° = 72°
This is B and D. You only need one of these, so you divide by 2.
The answer is 36°.
Hope this helps :)
Answer:
The correct option is C.
Step-by-step explanation:
The least common multiple (LCM) of any two numbers is the smallest number that they both divide evenly into.
The given terms are
and
.
The factored form of each term is
![n^3t^2=n\times n\times n\times t\times t](https://tex.z-dn.net/?f=n%5E3t%5E2%3Dn%5Ctimes%20n%5Ctimes%20n%5Ctimes%20t%5Ctimes%20t)
![nt^4=n\times t\times t\times t\times t](https://tex.z-dn.net/?f=nt%5E4%3Dn%5Ctimes%20t%5Ctimes%20t%5Ctimes%20t%5Ctimes%20t)
To find the LCM of given numbers, multiply all factors of both terms and common factors of both terms are multiplied once.
![LCM(n^3t^2,nt^4)=n\times n\times n\times t\times t\times t\times t](https://tex.z-dn.net/?f=LCM%28n%5E3t%5E2%2Cnt%5E4%29%3Dn%5Ctimes%20n%5Ctimes%20n%5Ctimes%20t%5Ctimes%20t%5Ctimes%20t%5Ctimes%20t)
![LCM(n^3t^2,nt^4)=n^3t^4](https://tex.z-dn.net/?f=LCM%28n%5E3t%5E2%2Cnt%5E4%29%3Dn%5E3t%5E4)
The LCM of given terms is
. Therefore the correct option is C.
The variance of the binomial distribution of the number of households with landline service is 2.
<h3>What is the binomial probability distribution?</h3>
It is the probability of <u>exactly x successes on n repeated trials, with p probability</u> of a success on each trial.
The variance of the distribution is given by:
V(X) = np(1 - p)
In this problem, the parameters are given as follows:
n = 8, p = 0.504.
Hence the variance is given by:
V(X) = 8 x 0.504 x 0.496 = 2.
