I’m not gonna lie I don’t know the answer I’m just answering random questions to get points I’m so sorry

Answer:
This is known as Data dredging.
Step-by-step explanation:
In order for any statistical analysis to be significant, a researcher has to first generate a hypothesis.
Data dredging is trying to uncover patterns in data that can be presented statistically without devising a clear hypothesis by use data mining. It is also referred to as data fishing or p-hacking.
In this case any correlation (relationship between cause-effect)will be purely by chance.
Therefore, the investigator is Data dredging
The answer is 90°
The sum of all angle in a triangle is 180°
So,
180-(45+45)
= 180-90
= 90°
I hope this helps you
tgH=HJ/HK
angle H+angle K=90
H=K=45 degree
sin45=cos46 = square root of 2/2
