Answer:

11) Alternate Interior Angles

x=6

12) Vertical Angles

x=8

13) Consecutive Interior Angles

x=5

14) Corresponding Angles

x=9

Step-by-step explanation:

11) Alternate Interior Angles

18x+7=115

18x=115-7

18x=108

x=108÷18

x=6

12) Vertical Angles

16x-8=15x

16x-15x=8

x=8

13) Consecutive Interior Angles

21x-5+80=180

21x+75=180

21x=180-75

21x=105

x=105÷21

x=5

14) Corresponding Angles

10x-3=87

10x=87+3

10x=90

x=90÷10

x=9

Such a study is used to remove the potential bias from the study. For example, if a subject is told that he is given a caffeine pill his actions will re-enforce that he has taken the pill, even in the case when he is given a placebo instead of actual pill. So the belief of the subject may cause bias in the result. This is removed by using the double blind study.

Also, since the experimenter also does not know which subject received the treatment, they won't act in different ways towards different subjects to give away any hints or clue. If the experimenter knows which subjects is given actual treatment, he may behave differently with him. So the double blind study removes this sort of bias as we..
