Web2 days ago · You know the lengths of all the sides but none of the angles. Rearranging the cosine rule equation gives the length of one of the sides. c = a2 + b2 - 2 ab cos C. Rearranging the equation: C = arccos ( ( a2 + b2 - c2) / 2 ab) The other angles can be worked out similarly. The cosine rule. WebWe know that the sum of the angles of a triangle adds up to 180°. Therefore, the unknown angle can be calculated using the formula Sum of interior angles of a triangle = Angle 1 + Angle 2 + Angle 3 ⇒ 180° = 45° + 63° + Angle 3 ⇒ Angle 3 = 180° - (45° + 63°) Angle 3 ⇒ 72° ∴ The third angle is 72°.
