Geometry and Trigonometry practice question
In a right triangle, which ratio gives the tangent of one of the acute angles?
- A. The length of the leg opposite the angle divided by the length of the leg adjacent to the angleCorrect
- B. The length of the leg opposite the angle divided by the length of the hypotenuse
- C. The length of the leg adjacent to the angle divided by the length of the hypotenuse
- D. The length of the hypotenuse divided by the length of the leg opposite the angle
Answer: A. The length of the leg opposite the angle divided by the length of the leg adjacent to the angle
Tangent is opposite over adjacent.
Why the other answers are wrong
- B. The length of the leg opposite the angle divided by the length of the hypotenuse
- Opposite over hypotenuse is the sine.
- C. The length of the leg adjacent to the angle divided by the length of the hypotenuse
- Adjacent over hypotenuse is the cosine.
- D. The length of the hypotenuse divided by the length of the leg opposite the angle
- Hypotenuse over opposite is the reciprocal of the sine.
