Draw a triangle to represent the situation illustrated above. What kind of triangle you get? What are the trigonometric relations valid for this problem? So, how far is the ship from the lighthouse? Calculate using one of the trigonometric ratios for any triangles (sine law). Hands-on! ACTIVITY Challenge you to solve another problem in measuring inaccessible points. Suppose you are on a deserted beach, and this beach you can see two islands: M and N. You score two points on the beach 100 m distant, with an instrument to measure angles (theodolite), measures the angles as pictured. What is the distance between the islands M and N? Design: Patricia Carla Mucelin According Crossfield (2004), the calculation of distances inaccessible was a common problem presented in the textbooks of mathematics from the beginning of the nineteenth century. That, when the students learned a type of trigonometry called Heights and Distances, or " Altimetry and Longimetry We will work with a problem related to this matter?

Nacrtajte trokut za zastupanje Situacija u gornjoj tablici. Kakav trokuta ste dobili? Koji su trigonometrijske odnosi vrijede za ovaj problem? Dakle, koliko je brod od svjetionika? Izračunajte pomoću jednog od trigonometrijske omjere za bilo trokuta (sine Zakon). Hands-on! AKTIVNOST Vas izazov riješiti još jedan problem u mjerenju nedostupan točke. Pretpostavimo da ste na napuštenoj plaži, i ova plaža možete vidjeti dva otoka: M i N. Vi rezultat dvije točke na plaži 100 m udaljene, s instrumentom za mjerenje kutova (teodolit), mjeri se kutovi, kao na slici. Što je udaljenost između otoka M i N? Dizajn: Patricia Carla Mucelin Prema Crossfield (2004), izračun udaljenosti nepristupačnim je čest problem predstavljen u udžbenicima matematike s početka devetnaestog stoljeća. Da, kada su učenici naučili vrstu trigonometrije zove visine i udaljenosti, ili " Altimetrija Longimetry Mi ćemo raditi s problemom u vezi s ovim pitanjem?
