if each exterior angle of a polygon is 45 degrees, what is the sum of the interior angles?
hint: what do we need to know to find the sum of the interior angles of a triangle? what can we determine about a polygon from knowing the measure of each of its exterior angles

1080 degrees.

Step-by-step explanation:

The sum of the exterior angles of all polygons add up to 360 degrees

So this polygon has  360 / 45 = 8 sides and 8 interior angles.

Each interior angle = 180 - 45 = 135 degrees ( adjacent angles).

So the sum of the interior angles = 8 *135 = 1080 degrees.

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
