Bourne. In the last section, Sine, Cosine, Tangent and the Reciprocal Ratios, we learned how the trigonometric ratios were defined, and how we can use x-, y-, and r-values (r is found using Pythagoras' Theorem) to evaluate the ratios. Now we'll see some examples of these ratios. Finding Exact Values of … WebTo find these angles we have to draw a right-angled triangle, in which one of the acute angles will be the corresponding trigonometry angle. These angles will be defined with respect to the ratio associated with it. For example, in a right-angled triangle, Sin θ = Perpendicular/Hypotenuse or θ = sin -1 (P/H) Similarly, θ = cos -1 (Base/Hypotenuse) solicitors dealing with tenancy issues
