We only need to find the heights of the 2 points on the flagpole and then subtract them. We have that AC and DC are related by the following trigonometric number: tan60=AC/DC. This is because ADC is a right triangle and AC is the opposite leg of the angle we know, while DC is the adjacent leg.
.
Thus, we have calculated AC. The same remarks apply to the triangle BCD; However, now we get that tan30=BC/DC.
.
Hence, the height of point B is 5 feet, while the height of point A is 15 feet. Their distance is 10 feet.

Chenoa starts with $250 in her saving account and each month she adds $15 in her saving account.
Therefore, we obtain a sequence as:
250, (250+15), (250+15+15),...
250, 265, 280,....
So, we get the first term () as 250.
Now , we can clearly observe that the first term is 250 and second term is obtained by adding 15 to the first term that is 265 and so on.
Similarly in an arithmetic progression, last term is and its previous term is
.
Similarly, will be obtained by adding 15 to its previous term
.
So, and
=250.
Therefore, Option C is correct.
