Answer:
60 degrees
Step-by-step explanation:
A triangle is 180 degrees and there is already 40 and 80 degrees.
So... 180-80-40=60 degrees.
Hope this helps :D
Line 1= undefined
Line 2= -4/3
Line 3= 4/3
Line 4= undefined
Line 5= 7/3
Line 6= -7/3
Line 7=no slope
Line 8=no slope
Line 9 =undefined
Line 10 = undefined
Line 11 = no slope
Line 12= undefined
NOTE: if the line is horizontal it have a zero slope or no slope and a vertical line the slope is undefined.
There are 5 20% in 100% ( 20 x 5 = 100)
So 10% of a number would be 12 x 5 = 60
Then there are 10 10% in 100% ( 10 x 10 = 100).
So if 10% = 60, then 100% = 60 x 10 = 600.
The starting value is 600
600 x 10% = 600 x 0.1 = 60
60 x 20% = 60 x 0.2 = 12
Now you have the starting value you can calculate the other answer:
600 x 20% = 600 x 0.20 = 120
120 x 10% = 120 x 0.10 = 12
The answer would be 12
