Answer:
Step-by-step explanation:
By the polygon exterior angle sum theorem, all the exterior angles of a polygon add up to equal 360 regardless of the number of sides it has. That means that 82 + 150 + b = 360 so
b + 232 = 360 and
b = 128

Answer:
-3-4x
Step-by-step explanation:
To complete the problem (5.2 - 4.5) - 5.5(4.8) you have to start with solving the numbers inside of the ( )'s.
Once you do this you should get .7 - 5.5(4.8).
Then you need to multiply to get .7 - 26.4.
Now all you have to do is simplify, -25.7
There you go! If you have any more questions about this or anything else just let me know! ;)
Multiply both sides by 30, to get rid of fractions... 12 + 30m = 25, subtract both sides by 12... 30m = 13. Divide both sides by 30, m = 13/30
