About This Quiz
Ramp and Incline Design - Quiz

Ramps aren’t just about accessibility — they’re precision-engineered structures based on slope and angle. In this quiz, you’ll calculate incline angles, rises, and lengths using trigonometry. From gentle wheelchair ramps to steep construction inclines, you’ll learn how math ensures safety, comfort, and compliance with design standards. By the end, you’ll... see moreunderstand how simple ratios create smooth and functional slopes everywhere around us.

2) A ramp makes a 12° angle with the ground and is 5 m long. What vertical height does it rise to (nearest tenth)?

Explanation

Rise = 5·sin12° ≈ 1.04 m → 1.0 m.

Submit

3) An accessibility ramp must rise 0.9 m over a horizontal run of 7 m. Find its angle.

Explanation

θ = arctan(0.9/7) ≈ 7.33° → 7°.

Submit

4) A ramp has an incline of 10°. If the horizontal run is 12 m, what is the rise (nearest tenth)?

Explanation

Rise = 12·tan10° ≈ 2.12 m → 2.1 m.

Submit

5) A 6 m long ramp rises 1.5 m. Find its angle (nearest degree).

Explanation

θ = arcsin(1.5/6) ≈ 14.48° → 14°.

Submit

6) A 10 m long ramp makes an angle of 20°. How high does it rise?

Explanation

Rise = 10·sin20° ≈ 3.42 m → 3.4 m.

Submit

7) A ramp must rise 1.5 m at a 12° angle. Find the ramp’s length.

Explanation

Length = 1.5 / sin12° ≈ 7.21 m → 7.2 m.

Submit

8) A ramp rises 2 m over a horizontal run of 20 m. Find its angle.

Explanation

θ = arctan(2/20) ≈ 5.71° → 6°.

Submit

9) A 15 m ramp makes an angle of 18°. Find the rise.

Explanation

Rise = 15·sin18° ≈ 4.64 m → 4.6 m.

Submit

10) A ramp must rise 0.6 m at a 7° angle. Find its horizontal run.

Explanation

Run = 0.6 / tan7° ≈ 4.89 m → 4.9 m.

Submit

11) A 20 m ramp makes an angle of 25°. Find its vertical rise.

Explanation

Rise = 20·sin25° ≈ 8.45 m → 8.5 m.

Submit

12) A 12 m long ramp makes an angle of 15°. Find the rise.

Explanation

Rise = 12·sin15° ≈ 3.11 m → 3.1 m.

Submit

13) A ramp must rise 1.5 m with a 6° angle. Find its length.

Explanation

Length = 1.5 / sin6° ≈ 14.36 m → 14.4 m.

Submit

14) A ramp must rise 3 m over a 20 m horizontal distance. Find its angle.

Explanation

θ = arctan(3/20) ≈ 8.53° → 9°.

Submit

15) A ramp rises 1.2 m over a horizontal distance of 10 m. Find its angle of inclination.

Explanation

θ = arctan(1.2/10) ≈ 6.84° → 7°.

Submit

16) A 4 m long ramp rises 1 m vertically. Find its angle of inclination.

Explanation

θ = arcsin(1/4) ≈ 14.48° → 14°.

Submit

17) A ramp rises 0.5 m and makes an angle of 5°. Find the horizontal run (nearest tenth).

Explanation

Run = 0.5 / tan5° ≈ 5.72 m → 5.7 m.

Submit

18) A ramp has a 9° angle and a 6 m horizontal run. Find its vertical rise.

Explanation

Rise = 6·tan9° ≈ 0.95 m → closer to 1.0 m.

Submit

19) A ramp must rise 2.4 m with a 10° angle. Find its horizontal run.

Explanation

Run = 2.4 / tan10° ≈ 13.61 m → 13.6 m.

Submit

20) A 25 m long ramp makes an angle of 30°. Find the rise.

Explanation

Rise = 25·sin30° = 12.5 m.
