Question

what is trigonometry?
what is it ratio?
​

Answer 1

Step-by-step explanation:

The trigonometric ratios are special measurements of a right triangle (a triangle with one angle measuring 90° ). ... There are three basic trigonometric ratios: sine , cosine , and tangent . Given a right triangle, you can find the sine (or cosine, or tangent) of either of the non- 90° angles.

Answer 2

• Trigonometry, the branch of mathematics concerned with specific functions of angles and their application to calculations.

• A ratio shows how much of one thing there is compared to another.
