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

In Which set do all of the values make the inequality 2x-1<10 true

Step2247 [10]

X<5.5, x has to be less than 5.5 because you add 1 to both sides and then divided both sides by two and you would get x < 5.5

Arlington ISD needs to construct a handicap ramp for one of its new buildings under construction. One point on the construction

Marat540 [252]

The slope of the handicap ramp is 1/2

The slope of the handicap ramp is gotten from the equation for the slope of a line, m with endpoints (x₁, y₁) and (x₂, y₂).

m = (y₂ - y₁)/(x₂ - x₁)

Since one point of the ramp can be identified by the ordered pair (d, 4d) and another point on the ramp is identified by the ordered pair (3d, 5d), we have that (x₁, y₁) = (d, 4d) and (x₂, y₂) = (3d, 5d).

Substituting the values of the variables into the equation, we have

m = (y₂ - y₁)/(x₂ - x₁)

m = (5d - 4d)/(3d - d)

m = d/2d

m = 1/2

So, the slope of the handicap ramp is 1/2
