Geometry and Trigonometry practice question
A ramp rises 5 metres over a horizontal run of 12 metres. What is the tangent of the angle the ramp makes with the ground?
Answer: 5/12
Tangent = opposite/adjacent = rise/run = 5/12.
Common wrong answers
- If you answered 12/5
- 12/5 is run over rise, the tangent upside down.
- If you answered 5/13
- 5/13 is the SINE (rise over the 13-metre sloped length).
- If you answered 12/13
- 12/13 is the COSINE.
