A line is 180° so if you are given 43°on part of line l
180-43=137
So x=137°
11 blue
2 green
7 brown
total is 20 card
7 out of that 20 are brown
so x out of 100% are brown
7/20=x/100 - cross multiply
700=20x
x=700/20
x=70/2
Answer:
Domain: {x|-∞<x<∞}
Range: {y|-∞<y≤3}
Transformation: Reflection across x-axis, left 2, up 3, vertical stretch of 2
