The document is a student's presentation summarizing the steps to solve a trigonometry problem about determining the height of lights on a building from an observer's perspective. The presentation shows setting up the tangent ratio equation using the given information of the observer being 2 miles from the building at a 5 degree angle of elevation. The student uses trigonometric functions to isolate and solve for the variable, determining the height of the lights is approximately 900 feet above the ground.
