Question

A woman entering a glass elevator on the ground floor of a hotel glances up to the top of the building across the street and notices that the angle of elevation is 48º She rides the elevator up three floors (50 feet) and finds that the angle of elevation to the top of the building across the street is 30º. How do I illustrate this?

Answer 1

This is how I picture the first part of the question, but I can' figure out where on the triangle to draw the second part of the question, regarding the upward distance of 50 feet, while maintaining a triangle drawing.
