What is the value of X in this polygon?

The answer to your question is x = 10

Step-by-step explanation:

To find the sum of the external angles in a polygon use the formula

                    180(n - 2)/n

n = number of sides

In this polygon n = 6 so,

                    180(6 - 2)/6 = 180(4)/6 = 720/6 = 120

Then

        2x + (x + 10) + (2x) + (x + 10) + (x + 16) + (x + 4) = 120

Simplification

         2x + x + 2x + x + x + x = 120 - 10 - 10 - 16 - 4

                                          8x = 80

                                            x = 80/8

Result

                                            x = 10

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

the probability that a bird is green (.30) is true
