How to solve a triangle in trigonometry
WebSolution of triangles ( Latin: solutio triangulorum) is the main trigonometric problem of finding the characteristics of a triangle (angles and lengths of sides), when some of these … WebTo solve the triangle we need to find side a and angles B and C. Use The Law of Cosines to find side a first: a 2 = b 2 + c 2 − 2bc cosA a 2 = 5 2 + 7 2 − 2 × 5 × 7 × cos (49°) a 2 = 25 + 49 − 70 × cos (49°) a 2 = 74 − 70 × 0.6560... a 2 = 74 − 45.924... = 28.075... a = √28.075... a = 5.298... a = 5.30 to 2 decimal places
