Find the measure of one interior angle in the given polygon below. round your answer to the nearest hundredth, if needed.
does the polygon have to be "regular" in order for you to be able to find just one interior angle? explain.
**must show all work, and provide an explanation using complete sentences for credit. regular heptagon

  128.57°

Step-by-step explanation:

A regular heptagon is a 7-sided polygon whose 7 interior angles all have the same measure. The measure of each of them in degrees can be computed from the formula

  interior angle measure = 180(n-2)/n . . . where n = 7 is the number of sides

  interior angle measure = 180(5/7) = 128 4/7 ≈ 128.57

The measure of one interior angle of a regular heptagon is about 128.57°.

The polygon does not have to be regular to find an interior angle. It needs to be of such a nature that the interior angles are known from the description of the polygon. For example, an isosceles right triangle is not a regular polygon, but you know that the measure of one acute angle is 45°.

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560

i believe that the answer is

b. y-1=-2(x-4)

hope this !
