Let O be the center of a circle. If <span>the measure of arc RS is 84 degrees, then m∠SOR=84^{0}. The triangle SOR is isoscales (because SO=OR as radii), so m∠RSO=m∠ORS=(180^{0}-84^{0}):2=48^{0}.
</span>
Line RU is tangent to the circle in point R, this means that m∠ORU=90^{0}.
Consider the triangle SRU. m∠RSU=30^{0} and m∠SRU=48^{0}+90^{0}=138^{0}, then m∠RUS=180^{0}-30^{0}-138^{0}=12^{0}.
ANSWER: Correct choice B - 12^{0}.

Answer: The answer is A.
Step-by-step explanation: The population of interest is defined as the population that you are drawing an inference (or conclusion) about. Usually, you cannot obtain the data for the whole population of interest, rather you can only obtain data for a proportion of it and then make inference about the whole population.
In this question, we can see that the researcher considers the population of interest to be "students last semester at FIU", therefore, A is the best answer. Option B and D are too broad, while option C refers to the sample, not population of interest, of the study.

Step-by-step explanation:
i just foudn out you lips is the same skin as your eyes
Angles in a triangle add up to 180°
since the other two are 21 and 104, you add them together = 21 + 104 = 125
to make it 180, you take 125 away from 180 = 180 - 125 = 55<span>°
</span>so angle F = 55°
