WebTrigonometry involves calculating angles and sides in triangles. Labelling the sides The three sides of a right-angled triangle have specific names. The hypotenuse (\ (h\)) is the … WebMar 26, 2016 · Locate the two sides that you use in the trig ratio. Because you are finding the sine of. you need the opposite side and the hypotenuse. For this triangle, (leg) 2 + (leg) 2 = (hypotenuse) 2 becomes f2 + k2 = r2. Plug in what you know to get f2 + 7 2 = 14 2. When you solve this for f, you get. Find the sine.
