WebSine, Cosine and Tangent. Sine, Cosine and Tangent (often shortened to sin, cos and tan) are each a ratio of sides of a right angled triangle:. For a given angle θ each ratio stays the same no matter how big or small the triangle is. To calculate them: Divide the length of one side by another side WebSolution: We 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°.
