This might have an answer to your Q http://www.mathleague.com/help/geometry/polygons.htm#octagon
135 degrees
<thought process: An ocatagon has 8^2 edges (this includes internals) diagonal vertices are all non-internals (including face vertices) only 3 vertices are connected by edges to form structure so: > (8^2)-3 = 64-3 = 61
The total degrees between 45 degrees and -5 degrees is 50 degrees.
7 degrees is colder than 3 degrees by 4 degrees.
20 degrees Celsius = 68 degrees Fahrenheit 30 degrees Celsius = 86 degrees Fahrenheit.
180 degrees - 100 degrees - 40 degrees = 40 degrees
30 degrees.
148 degrees minus 75 degrees is 73 degrees
6.8 degrees Centigrade IS degrees, degrees Centigrade.
It is -4 degrees.
The complement of 60 degrees is 30 degrees. Then the supplement of 30 degrees is 150 degrees. Answer: 150 degrees
Assuming you mean 84 degrees: 90 degrees - 84 degrees = 6 degrees. 6 degrees is your answer.
