Answer:
255 ft
Explanation:
We will use trigonometry to solve this.
From the angle we will use the side provided and the side we want to find. The side provided is adjacent to the angle. The side we want to find is opposite to it. Thus, we will use tan because tan uses opposite/adjacent.
This means that tan60 = x/144
tan60 * 144 = x
x = 255
The width of the pond is 255 ft.
