I think it would be the first option

Adding up the lengths of the exposed sides of the square would give you 40. You do not count the sides of the square in the middle because it's being covered by the 2 half circles.

We can use the 2 squares to measure the half circles. Since the circles cover 2 sides of the square, the circle is 20 units long on the flat side. To find the perimeter of the curves, you would at Pi into the equation.

From the lighthouse 1000 ft above sea level the angle of depression to boat a is 29 degress.a little bit later the boat moved cl
AnnyKZ [126]

Answer: The boat moved 768.51 feet  in that time .

Step-by-step explanation:

Since we have given that

Height of the lighthouse = 1000 feet

Angle depression to boat 'a' = 29°

Angle of depression  to shore 'b' = 44°

Consider ΔABC,

\tan 44\textdegree=\frac{AB}{BC}\\\\\tan 44\textdegree=\frac{1000}{BC}\\\\BC=\frac{1000}{\tan 44\textdegree}\\\\BC=1035.53\ feet

Now, Consider, ΔABD,

\tan 29\textdegree=\frac{AB}{BD}\\\\\tan 29\textdegree=\frac{1000}{BD}\\\\BD=\frac{1000}{\tan 29\textdegree}\\\\BD=1804.04\ feet

We need to find the distance that the boat moved in that time i.e. BC

so,

DC=BD-BC\\\\CD=1804.04-1035.53\\\\CD=768.51\ feet

Hence, the boat moved 768.51 feet  in that time .
