Since the 2 pentagons are congruent, then the sides are also congruent. Which means that side CD is equal to side GH:

CD = GH

3 x – 5 = 7 x – 17

Simplifying:

4 x = 12

Find the sum (the total measure) of the interior angles of an Octagon. Show all of your work
tatiyna
One way to do this is use the fact that the exterior angles of all polygons add up to 360 degrees
So an exterior angle of a regular octagon  = 360 / 8 = 45 degrees.
So each interior angle = 180 - 45 = 135 degrees

so total measure of all angles in octagon = 8 * 135 =  1080 degrees
