Sea is the correct answer
Answer:
Step-by-step explanation:
The relevant relations here are ...
The given arc CD is part of the semicircular arc CDA. The remaining arc, DA, is the supplement of CD:
arc DA = 180° -CD = 180° -125° = 55°
Central angle AOD has the same measure, 55°. That is one of the acute angles in right triangle AOB, so the other one is the complement of 55°.
∠ABO = 90° -∠AOB = 90° -55°
∠ABO = 35°
In right triangle ABC, angle ABC is given as 55°. The other acute angle, ACB, will be the complement of this.
∠ACB = 90° -∠ABC = 90° -55°
∠ACB = 35°
In the figure, angles ABO and ACB have measures of 35°.
Answer: David conducted (an observational study) because (it studies human behavior) and (the sample is not manuipulated).

In the triangle:
Now we know that:
Using the Law of Sines
D, 65 is a multiple of 13
