The shift in angle of the tree across the river they measure is 10. Surveying is all trigonometry. Often one surveyor operates equipment on a tripod while another holds up a rod some distance away. Trigonometry is used when measuring the height and angles of land . Use t a n x = o a t a n 70 = z 50 Step 2 Make z the subject by multiplying both sides by 50. z = 50  t a n 70 z = 137.4 m Step 3 Assume the man&#x27;s eye-level is (approximately) 1.7 m above the ground. It is the art of measuring horizontal . Surveyors use the tangent function a lot. The probably most well known use is the calculation of the distance of a star using the parallax method: Throughout the year as the Earth orbits the Sun, a star&#x27;s apparent position appears to move slightly relativ. Trigonometry is a study of the relationship between angles, lengths and heights. To measure Everest, Waugh&#x27;s surveyors used a method called triangulation. From engineers too logging workers, trigonometry is used all over the world. How is music related to trigonometry? Astronomers use trigonometry to calculate how far stars and planets are from Earth. The field emerged during the 3rd century BC, from applications of geometry to astronomical studies. Trigonometry also contains an understanding on natural laws and mathematical expressions that can be used to assist in engineering. Trigonometry is the branch of mathematics dealing with the relations of the sides and angles of triangles and with the relevant functions of any angles. This &quot;proto-trigonometry&quot; is equivalent to the trigonometry developed by ancient Greek astronomers. Step 4 Answer (1 of 2): In math, there is a concept called a vector.
