11. f = 180-(75+65)
f = 180 - 140
f = 40°
12. x = 62+51
x = 113
y = 180- 113
y = 67°
13. x = 360-(100+95+60)
x = 360 - 255
x = 105°

We notice that the common ratio of teh sequence is 10, and that the first term is -0.56, then the recursive formula is:
1.3-slope
6/3 just divide if you need to put it in a decimal-A
6/9 again you can just divide to get the decimal-green line
7/12-a the graph
-6/4 -b
