The 2 lines are parallel, so the 2 sides(e.g. 1 and 2/ 3 and 49) add up = 180 and In this case the 2 sides are equal as u can see from the original diagram so the angle of 2 is 180-49=131.
To find the percent of increase get the difference between the prices and then divided by the oringinal price and then time that by 100

Answer: the answer is b.
Step-by-step explanation: if you read the graph, you will see number of square feet, X the third one over you will see 100 over 40 and if you duplicate both then you get 200 for the number of square feet and 80 minutes, I hop this helps ツ.
4 legged tables : x
3 legged stools : y
x + y = 20 y= 20 - x
4x + 3y = 68
Replace y by 20 - x so we only have one letter
4x + 3(20 - x) =68
4x + 60 - 3x =68
x + 60 = 68
x = 8
To find y replace x by 8
y = 20 - 8
y = 12
So you have 8 four legged chairs and 12 three legged stools.
Hope I helped!
