The value of tan A is not clear from the question.
However, sin A = sqrt[tan^2 A /(tan^2 A + 1)]
what is the value of sin 75 degree
You can use your trigonometric functions (sine, cosine, and tangent).
The answer depends on what solving is required: do you need to find the area, perimeter, angles, trigonometric rations?
It depends on what information you do have. The answer may not be in radical form but in terms of a trigonometric ratio.
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.
Trigonometric identities involve certain functions of one or more angles. These identities are useful whenever expressions involving trigonometric functions need to be simplified.
There are a few ways. First, there are a multitude of trigonometric tables which list the sines and cosines of a variety of values. if you now one trigonometric value of a number, you can find all the others by hand, and you can also use a Taylor series approximation to find a fairly accurate value. (In fact, many calculators use Taylor series to find trigonometric values.)

sin 0=13/85
In a trigonometric equation, you can work to find a solution set which satisfy the given equation, so that you can move terms from one side to another in order to achieve it (or as we say we operate the same things to both sides). But in a trigonometric identity, you only can manipulate separately each side, until you can get or not the same thing to both sides, that is to conclude if the given identity is true or false.
yes we can calculate it by using trigonometric equation (by finding tan θ).
The exact value of (\cos(40.7^\circ)) is not a simple rational number or a well-known trigonometric value. To find its numerical approximation, you can use a calculator, which gives (\cos(40.7^\circ) \approx 0.7578). For precise applications, it's best to use a calculator or software that can compute trigonometric functions.
Common methods used for resolving vector problems include graphical methods, algebraic methods, and trigonometric methods. Graphical methods involve drawing vectors on a coordinate plane, algebraic methods involve using equations to manipulate vector components, and trigonometric methods involve using trigonometric functions to find vector magnitudes and angles.
You can use them to find the sides and angles of a right triangle... just like regular trigonometric functions
The trigonometric functions give ratios defined by an angle. Whenever you have an angle and a side in right triangle, you can find all the other angles and sides using the six trigonometric functions and their inverses. The link below demonstrates the relationship between functions.
It is a trigonometric equation for a right triangle, to find a non-right-angle angle. Using SOHCAHTOA, it is the opposite side divided by the adjacent angle
I would recommend a MATH BOOK.
