Respuesta :

Tangent is the trigonometric ratio of opposite side over adjacent side for an acute angle in a right triangle.

Sine is the trigonometric ratio of opposite side over hypotenuse for an acute angle in a right triangle.

Cosine is the trigonometric ratio of adjacent side over hypotenuse for an acute angle in a right triangle.

Hypotenuse is the longest side of a right triangle; the side that is opposite to the right angle.

In a right angled triangle, we have

  • a right angle and
  • hypotenuse, a side which is opposite to the right angle and the longest side of the right triangle.

If we consider an angle other than the right in this right triangle, then we can define the ratios sine, cosine and tangent of this angle with the help of the hypotenuse and its opposite and adjacent sides.

If x is the angle, then:

  • sin x = opposite side/hypotenuse.
  • cos x = adjacent side/hypotenuse.
  • tan x = opposite side/ adjacent side.

Here, sine is represented as 'sin', cosine is 'cos' and tangent is 'tan'.
