The adjacent side or base of the triangle.
In a right triangle, the cosine of an angle is defined as the ratio of the adjacent side of that angle to the hypotenuse.
It is a non-linear function of theta.
For a right angle triangle:- hypotenuse = adjacent/cosine or hypotenuse = opposite/sine
mathematical equation
The cosine function is mathematical equation to determine the adjacent angle of a triangle. The cosine of an angle is the ratio of the length of the hypotenuse: so called because it is the sine of the co-angle.
The cosine function on a right triangle is Adjacent leg divided by the hypotenuse of the triangle.
In a right angle triangle it is: cosine ratio = adjacent/hypotenuse
Fora right angle triangle: cosine angle = adjacent/hypotenuse
In a right triangle, the cosine of an angle is defined as the ratio of the adjacent side of that angle to the hypotenuse.
It is a non-linear function of theta.
The sine, cosine and tangent are used to find the degrees of a right angle triangle.
For a right angle triangle:- hypotenuse = adjacent/cosine or hypotenuse = opposite/sine

Use either the Sine or Cosine rules depending on the information you know about the triangle.
