Question

Help please it’s urgent, don’t know how to do this

Answer 1

`611\:\text{ft}`

Explanation:

In a right triangle only, the tangent of an angle is equal to its opposite side divided by its adjacent side. In this angle marked as
`42^(\circ)` is actually the same as the angle with point
`P`.

Therefore, we can set up the following equation:

`\tan 42^(\circ)=(550)/(x)`, where
`x` is the distance from the coast.

Solving, we get:

`x=(550)/(\tan 42^(\circ)),\\x\approx610.84\approx \boxed{611\:\text{ft}}`
