Answer:
Degree
Step-by-step explanation:
588 because that's the surface area minus the lide
(7-1/8) - (1-7/8) = 57/8 -15/8 = 21/4
45.864, because 57.33 divided by 100 is 0.5733 that multiplied by 80 is 45.864
Answer:
Each interior angle = 135 degrees,
Step-by-step explanation:
The exterior angles of all convex polygons add up to 360 degrees.
So for a regular octagon each exterior angle = 360 / 8
= 45 degrees.
Therefore each interior angle = 180 - 45 = 135 degrees,
