The distance from Nisha's apartment building to a sculpture in a park across the street is 222.76 ft. You can solve for how far away the building is from the sculpture using trigonometric functions. Trigonometric functions are the basis of trigonometry. This branch of mathematics studies the sides and angle relationships of triangles. The main functions in trigonometry are Sine, Cosine, and Tangent.

Further Explanation

a. Draw the Scenario:

Nisha's apartment building forms a right triangle with the sculpture in the park. Draw the scenario by using the steps below to guide you.

The top of Nisha's window is the height from the ground of the triangle, 90 feet. The distance between Nisha's building and the sculpture is the distance you need to find. How far away forms the base of the triangle and is labeled with the variable x.  The angle of depression is the angle formed downward from the horizontal line of sight from Nisha's window.

b. Choose the function

Trigonometry has three main functions: sine, cosine, and tangent. Each function describes a ratio between the opposite, adjacent and hypotenuse sides of a triangle using a reference angle.

Sine is the ratio of sides opposite over hypotenuse to the angle.Cosine is the ratio of sides adjacent over hypotenuse to the angle.Tangent is the ratio of sides opposite over adjacent to the angle.

Here, use the angle of depression as the reference angle. The height is opposite the angle of depression. The base, how far away from the sculpture, is the adjacent side of the angle. Use the tangent function.

c. Calculate and round your answer.

Use the definition of tangent and a calculator to find your answer.
