The sum of the interior angle measures of a convex polygon is 540° . How many sides does it have?

5!!

5 sides

Step-by-step explanation:

A polygon includes the shape pentagon which has  5 sides.

If  n  are number of sides of a convex polygon, sum of its interior angles is 540 degrees.

As in given case sum of interior angles is 540°, we have

( n  −  2 )  ×  180 °  =  540°

When we solve this equation, we get 5 sides.

We can check this by plugging 5 into n, so the equation is

(5 - 2) x 180°   = 540, this becomes...

3 x 180 = 540; this is correct so you answer is 5 sides.

step-by-step explanation:

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
