Final answer:
To find the distance from point AA to point BB, use trigonometry to calculate the heights of the lighthouse at the two points, and then subtract the heights to find the distance. We get 161.5 feet.
Step-by-step explanation:
To find the distance from point AA to point BB, we can use the concept of trigonometry and the tangent function.
The tangent of an angle is equal to the opposite side divided by the adjacent side.
In this case, the opposite side is the height of the lighthouse and the adjacent side is the horizontal distance from the boat to the lighthouse.
Using the given angle of elevation of 15° at point AA, we can calculate the height of the lighthouse by multiplying the horizontal distance (1032 feet) by the tangent of the angle.
So, height = 1032 feet × tan(15°)
= 268.4 feet.
Similarly, we can calculate the height at point BB using the given angle of elevation of 6°.
The height at point BB = 1032 feet × tan(6°)
= 106.9 feet.
Finally, to find the distance from point AA to point BB, we can subtract the heights at the two points.
Distance = 268.4 feet - 106.9 feet
= 161.5 feet.
