Answer: B. 1/4
Step-by-step explanation:BY/BC=2/4=1/2
Area ratio:
Area of triangle XBY / Area of triangle ABC = (BY/BC)²
=(1/2)²
=1/4
So the answer is B. 1/4
Answer:
The mean would best indicate the table size needed.
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.
