Find x and the indicated angle measurement

let's bear in mind that, the sum of all interior angles in a polygon is

180(n - 2),  n = number of sides in the polygon.

now, this is a PENTAgon, it has 5 sides, thus n = 5, so the sum of all interior angles is then, 180( 5 - 2) => 180(3) => 540°.

now let's add them up then.

step-by-step explanation:

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
