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 closer to the shore b and the angle of depression measures 44 degrees. how far has the boat moved in that time

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,

Now, Consider, ΔABD,

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

so,

Hence, the boat moved 768.51 feet  in that time .
