A boat heading out to sea starts out at Point A, at a horizontal distance of 639 feet from a lighthouse/the shore. From that point, the boat's crew measures
the angle of elevation to the lighthouse's beacon-light from that point to be
11°. At some later time, the crew measures the angle of elevation from point
B to be 3°. Find the distance from point A to point B. Round your answer to
the nearest foot if necessary.

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
