Question

How far off the coast, to the nearest foot, is the island?

Answer 1

SWe have that:

The height of the helicopter is the opposite side of the triangle formed.

How far off the coast to the helicopter is the adjacent side.

Therefore:

`tan48=(opposite)/(adjacent)`

Where:

opposite = 1250 ft

adjacent = d

Substitute the values:

`\tan48=(1250)/(d)`

Solve for d:

`d=(1250)/(\tan48)=1125.51`

Round to the nearest whole number 1126

Answer: d = 1126 ft
