While crossing the Atlantic, sailors spot two mermaids 120° apart on each end of an island that is 6 miles away. How far apart a

True [87]

Answer:

outer edge of the island is 20.8 miles

Step-by-step explanation:

As shown in figure sailor spot two mermaids at point B and C. BC is the outer edge of island. Point A represents sailors

AD=6 miles is perpendicular bisector of BC.

It is clear that

$\angle A=120 $^{\circ}$$

and

$\angle BAD=\angle CAD=60$^{\circ}$$

we will find BD and DC

in $\triangle BAD$

$tan 60$^{\circ}$$ = $\frac{BD}{AD}$

$\sqrt 3=\frac{BD}{6}$

$BD=6\times \sqrt 3$

Similarly, in $\triangle CAD$

$tan 60$^{\circ}$$ = $\frac{CD}{AD}$

$\sqrt 3=\frac{CD}{6}$

$CD=6\times \sqrt 3$

Therefore outer edge of the island,

$BC=BD+CD$

$BC=6\times \sqrt 3+6\times \sqrt 3$

$BC=12\times \sqrt 3$

$BC=12\times 1.73$

$BC=20.76$

$BC=20.8 miles$
