WebbIt 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. The general rule is: When we know any 3 of the sides or angles we can find the other 3 WebbThe sides of the triangle are in the ratio 3:4:5. The perimeter is 840 m. Find its area. Solution: Let the sides of the triangle be 3 x, 4 x, and 5 x respectively. We know that the perimeter = 840 m. 3 x + 4 x + 5 x = 840 12 x = 840 x = 840 12 = 70 So, the sides of the triangle are: 3 x = 3 (70) = 210 m 4 x = 4 (70) = 280 m 5 x = 5 (70) = 350 m
