subtract 90 from it and find the trig ratio of that and it will be equal to the trig ratio that is over 90 degrees
Sine and cosine.
To calculate the angles of a right triangle, you can use trigonometric ratios: sine, cosine, and tangent. For a triangle with an angle ( A ), you can find the sine (( \sin A )), cosine (( \cos A )), or tangent (( \tan A )) based on the lengths of the opposite, adjacent, and hypotenuse sides. Additionally, you can use the inverse trigonometric functions (arcsin, arccos, arctan) to find the angles given the lengths of the sides. Remember that the sum of the angles in any triangle equals 180 degrees, so if you know one angle is 90 degrees, the other two angles will sum to 90 degrees.
The word, trigonometry" is derived from trigon = triangle + metry = measurement. It is based on the study of angles of a triangle and their properties. Although trigonometric ratios are often introduced to students in the context of triangles, their properties for all angles.For example, trigonometric functions are well defined for angles with negative values as well as for more than 180 degrees even though no triangle can possibly have angles with such measures.
When finding missing side lengths in a right triangle using trigonometric functions, you typically apply ratios like sine, cosine, or tangent, which relate the angles to the lengths of the sides. Conversely, when calculating missing angle measures, you use the inverse trigonometric functions (such as arcsine, arccosine, or arctangent), which take the ratios of the sides and return the corresponding angles. Thus, the key difference lies in using direct ratios for side lengths and inverse functions for angles.
The sum of the angles is 180 degrees. So if the ratios are a, b and c then the angles are180*a/(a+b+c), 180*b/(a+b+c) and 180*c/(a+b+c) degrees.
Trigonometric ratios are characteristics of angles, not of lengths. And, by definition, the corresponding angles an similar triangles have the same measures.
Complements are defined for angles, not trigonometric ratios of angles.
Yes, since it has vertices it has angles and since it has angles it has trigonometric ratios
Sine and cosine.
For angles between 90 and 180 use the angle (180 - X) For angles between 180 and 270 use (X - 180) For angles between 270 and 360 use (360 - X) For angles greater than 360 subtract 360 until the angle is between 0 and 360 degrees and one of the above rules can be applied. You need to be careful with the signs of the ratios.

Six.
Because a right angle will always measure 90 degrees no matter what the dimensions of the triangle are.
There are two main uses. One is, in a complicated shape, to find the measure of an unknown angle using known values of other angles. The other is that trigonometric ratios are related to their supplement angles. Also, the sine of an angle is related to the cosine of of its complement.
