What is the cosine ratio?
Understand the Problem
The question is asking about the cosine ratio, which is a trigonometric function that relates the angle of a right triangle to the lengths of its adjacent side and hypotenuse. The cosine of an angle is defined as the ratio of the length of the adjacent side to the length of the hypotenuse.
Answer
The ratio of the adjacent side to the hypotenuse.
The final answer is the ratio of the adjacent side to the hypotenuse in a right triangle.
Answer for screen readers
The final answer is the ratio of the adjacent side to the hypotenuse in a right triangle.
More Information
The cosine ratio is one of the primary trigonometric ratios and is important for solving right triangles. It helps determine unknown side lengths or angles.
Tips
A common mistake is confusing the cosine ratio with sine or tangent. Remember, cosine uses the adjacent side and the hypotenuse.
