To find the length of the side of a triangle you use Sin, Cos, and/or Tan. Sin= The opposite side of the angle divided by the hypotonuse. Cos= The side adjacent to the angle divided by the hypotenuse. Tan= The side opposite of the angle divided by the adjacent side. If the angle is 30, and the hypotenuse or side you need to know is ten then the equation will look like this to find the side opposite of the angle. $${\mathtt{10}}{\mathtt{\,\times\,}}{\mathtt{Sin30}} = {\mathtt{X}}$$
