Look at the angles for all regular polygons. As the number of sides increases, do the measures of the angles increase or decreas
Verdich [7]

Answer:

As the number of sides increases, the measures of the angles increase

see the explanation

Step-by-step explanation:

we know that

The measure of the interior angle in a regular polygon is equal to

x=\frac{(n-2)}{n}(180^o)

where

n is the number of sides of the regular polygon

x is the measure of the interior angle in a regular polygon

we have that

<u><em>Examples</em></u>

<em>A triangle</em>

n=3 sides

x=\frac{(3-2)}{3}(180^o)=60^o

<em>A square</em>

n=4 sides

x=\frac{(4-2)}{4}(180^o)=90^o

<em>A pentagon</em>

n=5 sides

x=\frac{(5-2)}{5}(180^o)=108^o

<em>A hexagon</em>

n=6 sides

x=\frac{(6-2)}{6}(180^o)=120^o

so

n ----> 3,4,5,6...

x ----> 60°,90°,108°,120°,...

As the number of sides increases, the measures of the angles increase

The pattern is x=\frac{(n-2)}{n}(180^o)

Write an<br> explicit formula for an, the nth term of the sequence 39, 43, 47, ....
Inga [223]

9514 1404 393

Answer:

  an = 39 +4(n -1)

Step-by-step explanation:

The formula for the general term of an arithmetic sequence is ...

  an = a1 +d(n -1)

Here, the sequence has first term a1 = 39 and common difference d = 43-39 = 4. So, the general term is ...

  an = 39 +4(n -1)
