trigonometrically
Via angle calculations
In a way that uses or relates to trigonometry—the branch of mathematics dealing with the relationships between angles and sides of triangles.
The distance was calculated trigonometrically using known angles and a baseline measurement.
The word appears mainly in technical and scientific contexts.
