Answer:
12
Step-by-step explanation: we will use pathogorean theorem because there is a right triangle. a^2+b^2=c^2
We know BE=9 we need AE to find AB
You can make another triangle on the end. AD=28 - 12 (BC) = 16
16/2 = 8 so AE= 8
8^2+9^2=c^2
145=c^2
Square root of 145=c
C=12.04

Hope this helps!
angle 2 and angle 6 are corresponding angles.
Since the lines crossed by the trnasversal are parallel, corresponding angles are congruent. (equal)
angle 6 = 106°
Answer:
The correct answer is the last on that’s states: it is not a valid sample because it is not a random sample of the population.
Step-by-step explanation:
When a researcher wants to know about the same thing, he/she has to take a sample from the population.
Example, consider a researcher wants to know how many hours the students study at home in a week, so the researcher has to take the sample from the student population.
Here, he/she gives the advertisement and offers $10 for 10 people. Therefore for anyone can come they might not required for a particular study.
Therefore, the answer is the last one.
