Ratios in Right Triangles Quiz (5 Questions)

1. True or False: sin θ = adjacent / hypotenuse.

2. For a right triangle, opposite = 5, hypotenuse = 13. Find sin θ.

3. If cos θ = 3/5, find sin θ using Pythagorean Theorem.

4. tan θ = opposite / adjacent. True or False?

5. Give a real-life example using trigonometric ratios.

Answer Key

1. False (opposite / hypotenuse)

2. sin θ = 5/13

3. sin θ = √(1 − (3/5)^2) = 4/5

4. True

5. Navigation, building slopes, measuring heights, engineering
