Answer:
The distance between the gabe and the base of the building is 726.07 meters.
Step-by-step explanation:
It is given that,
Gabe is sitting in his boat and sees a famous building onshore which is known to be 250 meters tall.
The angle of elevation, θ = 19°
We have to find the the distance between the gabe and the base of the building. From the attached figure, AB = height of building = 250 meters
BC = distance between the gabe and the base of the building
Using trigonometric equation as :



BC = 726.05 meters
So, the gabe is 726.05 meters away from the base of the building.
