Question

the sum of seven interior angles of an octagon is 1000 find the eight angle.

please answer

​​

Answer 1

Answer:

now, we're assuming this is for interior angles.

the sum of all the interior angles in a polygon is

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

now, this is an OCTAgon, it has OCTA=8 sides, so it has a sum of its interior angles at 180( 8 - 2) --> 180(6) ---> 1080°.

now, we already know seven of those eight angles add up to 1000, so... surely you'd know what the last one is.
