The exterior angles of any polygon will always add up to 360 degrees. Since we know all the values for every exterior angle, we can simply make the following equation:

3x + (x + 50) + 4x + (2x + 40) = 360

Simplify:

10x + 90 = 360
10x = 270
x = 27

If you want me to explain anything I did here, just ask :)

noname [10]
You can think of an hour and a half as 75% itself already because you have 3/4 or three thirty minute periods. So every 1/4 is a 30 minute period, and if you multiply 1/4 by 4 you get 4/4 which you ten can convert to 2 hours or 4, 30 minute time periods. (I’m sorry if I explained this in a very confusing manner). It will take Amelia 2 hours in total to finish her drawing.
