Trigonometry is used in physics. When you take physics, you will use the basic trig you're learning and use it to help calculate angles of trajectory, as well as in optics and statics. It is also used in geography, and in astronomy to help calculate the positions of stars relative to your position on earth. It is used in engineering. Surveyors use trigonometry all the time to calculate angles, distances, and positions of buildings and roads. See the below links for more details.

Trigonometry is a branch of mathematics. The subject is the study of triangles. The relation between the sides, angles and areas of trianglesand applications form the theme. It is combination of geometry ,algebra, analysis and other branches of maths and has applications from day today problems like height and distances to advanced sciences.Wave theory, astronomy and geographical measurements make use of trigonometry. Engineering sciences could do better because of it. Trigonometry is also helpful in navigation, building and structural engineering,accoustics and architectures,civil and mechanical engineering, computer graphics etc. Even musical sciences could find a place in its applications.
