Question

Why they never ask to find trignometric ratios form right angle itself?
If I'm about to find trignometric ratios from ∠B then which one should I consider "Oppsite side" and which one "adjacent side"?​

Answer 1

Answer:

Step-by-step explanation:

So far, we've only dealt with right triangles, but trigonometry can be easily applied to non-right triangles because any non-right triangle can be divided by an altitude * into two right triangles.A missing acute angle value of a right triangle can be found when given two side lengths. To find a missing angle value, use the trigonometric functions sine, cosine, or tangent, and the inverse key on a calculator to apply the inverse function (arcsin ⁡ , arccos ⁡ , arctan ⁡ ), sin−1 , cos−1 , tan−1 .
