Answer:
509.35 feet
Step-by-step explanation:
16°23' means 16 degrees and 23 minutes. A minute is 1/60 of a degree.
16°23' = 16 + (23/60) = 16.383°
Similarly:
49°29' = 49 + (29/60) = 49.483°
When the boat is first noticed:
tan(16.383°) = 200 / a
a = 200 / tan(16.383°)
a = 680.27
When the boat stops:
tan(49.483°) = 200 / b
b = 200 / tan(49.483°)
b = 170.92
So the difference is:
a − b = 680.27 − 170.92 = 509.35
The boat traveled 509.35 feet from the time it was first noticed to the time it stopped.
Blood types all have different antigens. People can only receive blood with the same antigens as theirs. Type A and B both have different distinct antigens. But because AB blood contains both A and B it can take blood from both those types. However, people with AB blood can also receive Type O blood because it lacks antigens entirely. Therefore, that makes AB the universal receiver.
