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,
Answer:
-12
Step-by-step explanation:
Answer:
1. she subtracted 4 from 20 when she was supposed to add it and get 24
4x-4=20
4x=24
x=6
Step-by-step explanation:
2. x+8_>5
what plus 8 equals a number equal to five
that would be -3
and any number above that since it is saying that the number can be equal to or greater than 5 when it is added together with 8
That the best way I can show my work.
