When driving west toward the Rocky Mountains, you see a peak $3.1^{\circ}$ above the horizon. Your GPS gives your current elevation as $1580 \mathrm{~m},$ and according to the map, you're $25.0 \mathrm{~km}$ (horizontally) from the peak. Find the peak's elevation.

Key Concepts

Unit Conversion

Unit conversion is the process of converting quantities from one measurement system to another to ensure consistency across calculations. In problems involving distances and elevations, converting units such as kilometers to meters is essential before applying trigonometric formulas.

Right Triangle Geometry

Right triangle geometry involves studying triangles with one 90-degree angle. The relationships among the sides and angles in these triangles allow for the use of trigonometry to solve for missing length measurements, which is useful in many applications including elevation calculations.

Elevation Measurement

Elevation measurement refers to determining the height of an object or a point relative to a reference level, typically sea level. It often involves using data from GPS and understanding the geometry of the terrain to accurately compute vertical differences.

Angle of Elevation

The angle of elevation is the angle between the horizontal line of sight and the line of sight upward to an object. It is used to relate vertical height differences with horizontal distances through the principles of trigonometry.

Trigonometric Functions

Trigonometric functions, particularly the tangent function in this context, relate the angle of a right triangle to the ratio of its opposite side to its adjacent side. This relationship is crucial for calculating unknown side lengths when the angle and one side are known.
