Answer:

85

because A is half of that and if you divided 170 by 2 you would get 85, I think that's how you do it.

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)

What do I type in the box pls help???
MaRussiya [10]

Answer:

f(x)=3x-5

g(x)=-6x²+6x+2

f(x)×g(x)

=(3x-5)(-6x²+6x+2)( use distributive property)

=(3x×-6x²)+(3x×6x)+(3x×2)+(-5×-6x²)+(-5×6x)+(-5×2)

=(-18x³)+(18x²)+6x+30x²-30x-10

=-18x³+18x²+6x-30x+30x²-10

=-18x³+18x²-24x+30x²-10

=-18x³+18x²+30x²-10

=-18x³+48x²-10---------------you may write this answer

Hope it's was clear,

please pick me brainliest
