I think it’s C as 425 X 0.0082 is 34.85

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)

Answer:

  (x, y) = (34/5, -4/5) = (6.8, -0.8)

Step-by-step explanation:

Subtract the first equation from the second to eliminate x.

  \left(\dfrac{x}{3}-\dfrac{y}{2}\right)-\left(\dfrac{x-5}{3}+\dfrac{y+2}{3}\right)=\left(\dfrac{8}{3}\right)-(1)\\\\y\left(-\dfrac{1}{2}-\dfrac{1}{3}\right)+\left(\dfrac{5}{3}-\dfrac{2}{3}\right)=\dfrac{5}{3} \qquad\text{partially simplify}\\\\-\dfrac{5}{6}y=\dfrac{2}{3} \qquad\text{subtract 1}\\\\y=-\dfrac{4}{5} \qquad\text{multiply by $-\dfrac{6}{5}$}

Substituting for y in the second equation, we can find x.

  \dfrac{x}{3}-\dfrac{1}{2}\left(-\dfrac{4}{5}\right)=\dfrac{8}{3}\\\\5x +6=40 \qquad\text{multiply by 15}\\\\5x=34\qquad\text{subtract 6}\\\\x=\dfrac{34}{5}

The solution is (x, y) = (34/5, -4/5) = (6.8, -0.8).

Two side lengths of a triangle are given as 9 cm and 5 cm. What could be the length of its third side? 3cm
disa [49]

The length of the third side could be 5 cm ⇒ 3rd answer

Step-by-step explanation:

There is a fact in any triangle, that the sum of the lengths of the

smallest two sides of a triangle must be greater then the length of

the largest side

The sum of smallest 2 sides > the 3rd side

So to solve the problem

1. Chose the third side from the answer

2. Add the lengths of the two smallest side

3. Compare between the sum and the 3rd side

∵ The length of the two sides of a triangle are 9 cm and 5 cm

- If the third side is 3 cm

∵ 3 and 5 are the smallest side

∵ 3 + 5 = 8

∵ 8 < 9

∴ The sum of the smallest two sides < the 3rd side

∴ 3 cm can not be the length of the 3rd side

- If the third side is 4 cm

∵ 4 and 5 are the smallest side

∵ 4 + 5 = 9

∵ 9 = 9

∴ The sum of the smallest two sides = the 3rd side

∴ 4 cm can not be the length of the 3rd side

- If the third side is 5 cm

∵ 5 and 5 are the smallest side

∵ 5 + 5 = 10

∵ 10 > 9

∴ The sum of the smallest two sides > the 3rd side

∴ 5 cm can be the length of the 3rd side

- If the third side is 14 cm

∵ 5 and 9 are the smallest side

∵ 5 + 9 = 14

∵ 14 = 14

∴ The sum of the smallest two sides = the 3rd side

∴ 14 cm can not be the length of the 3rd side

The length of the third side could be 5 cm
