Geometry and Trigonometry practice question
In a right triangle, tan A = 3/4, and the leg adjacent to angle A has length 8. What is the length of the leg opposite angle A?
Answer: 6
tan A = opposite/adjacent, so opposite = (3/4)(8) = 6.
Common wrong answers
- If you answered 3
- 3 copies the numerator of the ratio.
- If you answered 10
- 10 is the hypotenuse.
- If you answered 10.67
