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,

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 .
Answer:
2 hrs and 32 mins
Step-by-step explanation:
Step 1. Because Inez worked more we are going to start by subtracting the the minutes. 23-51= -28.
Step 2. Now we move on to the hours. 7-4= 3. Know we know that the hour time is going to be three. But wait!
Step 3. Because we can't have negative numbers, we need to subtract some more. 60-28= 32. Now I know that my minutes will be 32.
Step 4. But because we used a negative number we have to subtract another hour from our time.
Answer: 2 hrs and 32 mins
Hope this helps!
