Trigonometry is an extremely large field (and a branch of geometry) which deals with the elucidation of the sides of a triangle based on its angles. Some common trigonometric ratios (relating to a right-angled triangle) are as follows:
sine of an angle = length of opposite side/length of hypotenuse
cosine of an angle = length of adjacent side/length of hypotenuse
tangent of an angle = length of opposite side/length of adjacent side
Of course other trigonometric ratios exist, such as cotangent, cosecant, secant of the angles. In addition, formulae such as the Sine Rule and Cosine Rule exist to allow us to elucidate the length of an unknown side based on its opposing angle and at least one other side.
As this question is relatively vague, I'm afraid that I cannot provide any further assistance in this respect.

What is trigonometry and its formula?
Trigonometry is a whole branch of mathematics and does not comprise only one formula!
Is there a formula to work out trigonometry?

How is trigonometry used in land surveying?
Trigonometry is basically formula's to help you find out unknown sides and angles of a triangle. Surveying is measuring land. But as not all land is equal so these formula's are used to help.
What is is the formula called that you can use to work out a side length of a right angle triangle?
