The sum of the interior angles, s, in an n-sided polygon can be determined using the formula s = 180(n – 2), where n is the numb

disa [49]

Answer:

Equivalent equation of $s =180(n-2)$ is $n =\frac{s}{180}+2$

And the number of sides does a polygon have is, n =9.

Step-by-step explanation:

Given:

The sum of the interior angles, 's' in a n-sided polygon can be determined

using the formula is: $s =180(n-2)$ .....[1]

where n is the number of sides.

We can write the equivalent equation of [1]

$s = 180(n-2)$

Divide both sides by 180;

$\frac{s}{180} =\frac{180(n-2)}{180}$

Simplify:

$\frac{s}{180}=n-2$

Add 2 to both sides of an equation:

$\frac{s}{180}+2=n-2+2$

Simplify, we get;

$n =\frac{s}{180}+2$ ......[2]

Now, to find the value of n ;

Given: s =1260°

Substitute this value in [2] we get;

$n =\frac{1260}{180}+2$

n = 7+2 =9

Therefore, the number of sides in a polygon is, n=9

2. Which of the following (-6, 20), (-9, 1) or (14, 2) ) are a solution to the system of equations?: 2x + y = 8 5x + 2y=10

Leya [2.2K]

(-6, 20)

You can get this through elimination by multiplying the first equation by -2 to get the y values to cancel out.
