∙ 14y agoFor finding the angles in a right angled triangle the ratios are:
sine = opposite divided by the hypotenuse
cosine = adjacent divided by the hypotenuse
tangent = opposite divided by the adjacent

∙ 14y agoTangent = sine/cosine provided that cosine is non-zero. When cosine is 0, then tangent is undefined.
mathematical equation
use the inverse sine or cosine or tangent
It depends on what information you already have. For example, if you know the length of two sides of a triangle, you can easily find the tangent. Or, if you know the length of two angles and a side, you can find the other sides as well, using the tangent, cosine, and sine as needed.
Tangent (theta) is defined as sine (theta) divided by cosine (theta). In a right triangle, it is also defined as opposite (Y) divided by adjacent (X).

You can use your trigonometric functions (sine, cosine, and tangent).
you can use the sine, cosine, tangent formula.
Tangent = sine/cosine provided that cosine is non-zero. When cosine is 0, then tangent is undefined.
They are used to find the angle or side measurement of a right triangle. For example, if 2 sides of a right triangle have known values and an angle has a known measurement, you can find the third side by using sine, cosine or tangent.

It starts with the simple Right-Angled Triangle and its 3 simple ratios: Sine, Cosine, Tangent...
Sine = -0.5 Cosine = -0.866 Tangent = 0.577
Tangent (theta) is defined as sine (theta) divided by cosine (theta). In a right triangle, it is also defined as opposite (Y) divided by adjacent (X).
