When you progress through the course a little more, you'll learn that since all similar triangles have the same trig values and the 30-60-90 and 45-45-90 have special side ratios, you can get the trig values of angles in these triangles. For example, in a 30 - 60 - 90 triangle, the side lengths can be written as x - x*sqrt (3) - 2x.

Trigonometric Ratios. Using the concept of trigonometry, we can determine a triangle's remaining sides and angles when we know some of its sides and angles. This issue is resolved by applying some ratios of a triangle's sides to its acute angles. Trigonometric ratios of angles are what are referred to as these acute angle ratios.

Trigonometry ratios of complementary angles are the ratios related to trigonometry when their angles are complementary. Complementary angles are angles when the sum of angles is 90 degrees. Suppose we have two angles 'a' and 'b' that are complementary, then if sin a = x then sin b = y now cos a = y and cos b = x.

But what is this ratio from angle B's point of view? Well, the sine of angle B is going to be its opposite side, AC, over the hypotenuse, AB. So this right over here, from angle B's perspective, this is angle B's sine. So this is equal to the sine of 90 degrees minus theta. So the cosine of an angle is equal to the sine of its complement.
