Finding the area of a triangle trigonometry
WebTrigonometry is also useful for general triangles, not just right-angled ones . It helps us in Solving Triangles. "Solving" means finding missing sides and angles. Example: Find the Missing Angle "C" Angle C can be found using angles of a triangle add to 180°: So C = 180° − 76° − 34° = 70° We can also find missing side lengths.
