How to properly work out and solve this question using

The Law of Sines. 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. (Side a faces angle A, side b faces angle B and side c faces angle C). And it says that: When we divide side a by the sine of angle A it is equal to side b divided by the sine of angle B, and also equal to

Revision Topic 20 Sine and Cosine Rules and 3D Trigonometry

A sine is a trigonometric function. It is defined in reference to a right triangle, which is a triangle with a 90-degree angle in it. Either of the other angles (the angles that are less than 90-degrees) can be used to define certain functions, called "trigonometric functions." The sine of one of these angles is equal to the length of the side opposite that angle (the leg) divided by the
