Trigonometry finding sides

WebRachel explains how to use trigonometry to find the lengths of missing sides and the size of angles in right-angled triangles. WebIn a right triangle, the hypotenuse is the longest side, an "opposite" side is the one across from a given angle, and an "adjacent" side is next to a given angle. We use special words …

WebFeb 10, 2024 · For example, key in either 10 / (sin 40) or 10 / (40 sin), depending on your calculator. Using our example, we find that sin 40 = 0.64278761. To find the value of c, we simply divide the length of a by this number, and learn that 10 / 0.64278761 = 15.6, the length of our hypotenuse! Method 4. WebOne of the beauties of these trigonometric functions is that you can find two missing sides of a right triangle if you are given only one side and an acute angle. 1.
