Question
A lighthouse sits at the edge of a cliff, as shown. A ship at sea level is 825 meters from the base of the cliff. The angle of elevation from sea level to the base of the lighthouse is 37.2°. The angle of elevation from sea level to the top of the lighthouse is 38.3°. Find the height of the lighthouse from the top of the cliff.

Do not round any intermediate computations. Round your answer to the nearest tenth.

Note that the figure below is not drawn to scale.

**Diagram Explanation:**

- The diagram displays a right triangle formed by the line of sight from the ship to the base of the lighthouse, and another right triangle from the ship to the top of the lighthouse.
- The horizontal distance from the ship to the base of the lighthouse (adjacent side) is 825 meters.
- The angle of elevation to the base of the lighthouse is 37.2°, and the angle of elevation to the top of the lighthouse is 38.3°.
- The diagram includes the unknown height difference between the cliff's edge and the top of the lighthouse, which is what needs to be calculated.

There is a text box to input the computed height of the lighthouse in meters, followed by buttons labeled "Explanation" and "Check" for further interaction.
