A regular polygon

olga55 [171]

Answer:

3.6° = ext. angle

Step-by-step explanation:

For the shape to be a regular polygon, all interior angles must be congruent.

We can find every interior angle by using the formula:

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

$\frac{180(100-2)}{100}$

$\frac{180(98)}{100}$

$\frac{17640}{100}$

176.4 = each int. angle

We also know that int. and ext. angles are supplementary!

180 = 176.4 - x

3.6° = ext. angle

Find the area and perimeter.

lara [203]

Answer:

Step-by-step explanation:

Perimeter of triangle = 4x - 3 + x + 9 + 8

= <u>4x + x</u> -<u> 3 + 9 + 8</u>

= 5x + 14

Area = $\frac{1}{2}*base *height$

$= \dfrac{1}{2}*8*3x\\\\= 4 * 3x\\\\= 12x$
