sin formula to find angle The Law of Sines or Sine Rule is very useful for solving triangles a sin A b sin B c sin C It works for any triangle a b and c are sides A B and C are angles
The sine of an angle of a right angled triangle is the ratio of its perpendicular that is opposite to the angle to the hypotenuse The sin formula is given as sin Perpendicular Hypotenuse sin 2n sin for every sin sin Sin value table is given below Finding an Angle in a Right Angled Triangle Angle from Any Two Sides We can find an unknown angle in a right angled triangle as long as we know the lengths of two of its sides Example The ladder leans against a wall as shown What is the angle between the ladder and the wall The answer is to use Sine Cosine or Tangent But which one to use
