One exterior angle of a regular pentagon has a measure of (2x). What is the value of x?
777dan777 [17]

x = 36

pentagon has 5 sides . The formula n/360 gives you the measure of each angle in a regular polygon. So in this case n ( stands for number of sides) is 5. Sum of exterior angle of a any polygon is 360. The measure of 1 exterior angle is given. It is 2x.

Now using ALGEBRAIC EXPRESSIONS we can write it as 5/360 = 2x

which is 72=2x

which is 72/2 = x

which is 36 = x

so x = 36.

aleksandr82 [10.1K]

Answer:

\frac{1}{6}=0.16

Step-by-step explanation:

Given : There are six balls in bag

             Basketballs=2

             Playground balls =3

             Soccer ball =1

To Find : the probability that if you pick one of the balls without looking, it will be a soccer ball

Solution :

Total no. of balls = 6

No. of soccer balls = 1

Probability = favorable outcomes / total outcomes

Since total outcomes = total no. of balls =6

And favorable outcome = no. of soccer balls = 1

Thus , Probability of getting soccer ball = \frac{1}{6}

Hence the probability that if you pick one of the balls without looking, it will be a soccer ball:

\frac{1}{6}=0.16
