Remark

The sample was not voluntary. 284 people at random were selected. A is incorrect.

The question was a "yes/no" question. You either supported the motion, or you did not. One response did not influence the other. B is incorrect.

There's no data missing that can't be calculated. 20 people refused to answer for one reason or another. A very large number of people supported the pole so the 20 people would not make a difference no matter how they voted. Still the 20 people were not reported but could be calculated. The better answer is D. <<<< Answer.

You could say C but there are other possible reasons and a more general answer is needed.

Answer:

Step-by-step explanation:

This is a right triangle trig problem. Picture a right triangle. The height of the triangle is the height of the lighthouse, your distance from the base of the lighthouse is what we are solving for, and the reference angle is 2 degrees, which is the angle of inclination from where you stand to the top of this lighthouse. We have the reference angle, the side opposite the reference angle, and we are looking for the side adjacent to the reference angle. This is the tangent ratio: the side opposite the reference angle over the side adjacent to the reference angle. We know the measure of the reference angle and we know the value of the side opposite the reference angle. Filling in:

$tan(2)=\frac{200}{x}$ and
