Answer:
13.0 units
Step-by-step explanation:
To find the distance between two points, we use the formula
d = sqrt( (y2-y1)^2+ (x2-x1)^2)
sqrt((-3--10)^2 + (-12--1)^2)
sqrt( (-3+10)^2 + (-12+1)^2)
sqrt( (7^2 + (-11)^2)
sqrt( 49+121)
sqrt( 170)
13.038
Rounding to the nearest tenth

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.
