the angle of elevation from a ship to a 135-foot-tall lighthouse is 2 degrees. How far is the ship from the lighthouse?

Same type of problem as your previous one.

Let me know what you got

To find the distance between the ship and the lighthouse, we can use the tangent function. The tangent of an angle is equal to the opposite side divided by the adjacent side of a right triangle.

In this case, the opposite side is the height of the lighthouse (135 feet), and the angle of elevation is 2 degrees. We want to find the adjacent side, which represents the distance between the ship and the lighthouse.

The formula for the tangent function is:

tan(angle) = opposite / adjacent

Substituting the given values into the formula:

tan(2 degrees) = 135 feet / adjacent

Now, we can solve for the adjacent side:

adjacent = 135 feet / tan(2 degrees)

Using a scientific calculator, calculate the tangent of 2 degrees:

tan(2 degrees) ≈ 0.03492

Substituting this value back into the formula:

adjacent = 135 feet / 0.03492

Calculating this expression:

adjacent ≈ 3870.68 feet

Therefore, the ship is approximately 3870.68 feet away from the lighthouse.
