How to solve trigonometry triangle problems

WebFor a triangle with an angle θ , the functions are calculated this way: Example: what are the sine, cosine and tangent of 30° ? A 30° triangle has a hypotenuse (the long side) of length 2, an opposite side of length 1 and an adjacent side of √3, like this: Now we know the lengths, we can calculate the functions:
