The sum of the measures of the interior angles of a polygon is 2880°. How many sides does the polygon have?

harina [27]

Let

S------> The sum of the measures of the interior angles of a polygon

n-------> number of sides of a polygon

we know that

The formula to find the sum of the measures of the interior angles of a polygon is equal to

$S=(n-2)*180$ °

in this problem

$S=2880$ °

Solve for n

$S=(n-2)*180\\ \\ n=\frac{S}{180}+2\\ \\ n=\frac{2880}{180}+2\\ \\ n=16+2\\ \\ n=18\ sides$

therefore

the answer is

$18\ sides$

The length of s is 2/3 the length of t. If s has an area of 368 cm squared find the perimeter of the figure

ser-zykov [4K]

$s = \frac{2}{3}t
\\\ \frac{2}{3}t*t = \frac{2}{3}t^2
\\\ \frac{2}{3}t^2 = 368
\\\ t^2 = \frac {3}{2}368
\\\ t^2 = 552
\\\ t \approx 23.5
\\\ s \approx 15.6
\\\ P \approx 78.2$
