krok68 [10]

Answer:

The cosine of an angle is the ratio of the length of the leg adjacent to the angle to the length of the hypotenuse.

Step-by-step explanation:

  • In a right angled triangle, the cosine of an angle is the length of the adjacent side divided by the length of the hypotenuse.
  • Also it is the sine of the complementary angle.
  • The abbreviation is cos
  • The longest side of the triangle is called the hypotenuse,
  • The side opposite the angle theta is called the opposite side,
  • The third side is called the adjacent side.
  • Therefore, cos(\theta) = \frac{adjacent}{ hypotenuse}
