Geometry and TrigonometryMediumTangent from a hypotenuse and one leg
Geometry and Trigonometry practice question
A right triangle has a hypotenuse of length 26 and one leg of length 24. What is the tangent of the angle opposite the other leg?
Answer: 5/12
The other leg is √(676 − 576) = 10, so the tangent is 10/24 = 5/12.
Common wrong answers
- If you answered 12/5

- If you answered 5/13
- 5/13 is the sine of that angle.
- If you answered 12/13
- 12/13 is the cosine of that angle.
