Trigonometric Ratios Practice
📐 Part 1: Understanding Trigonometric Ratios
1. In a right-angled triangle, which ratio represents sine θ?
adjacent ÷ hypotenuse
opposite ÷ hypotenuse
opposite ÷ adjacent
hypotenuse ÷ opposite
2. What does the tangent ratio equal?
sin θ ÷ cos θ
cos θ ÷ sin θ
opposite ÷ hypotenuse
adjacent ÷ hypotenuse
3. In a right-angled triangle with angle θ = 30°, hypotenuse = 10 cm, which calculation finds the opposite side?
10 × cos(30°)
10 × sin(30°)
10 × tan(30°)
10 ÷ sin(30°)
4. A ladder leans against a wall at 60° to the ground. The ladder is 8 metres long. How high up the wall does it reach?
8 × sin(60°) ≈ 6.9 metres
8 × cos(60°) = 4 metres
8 × tan(60°) ≈ 13.9 metres
8 ÷ sin(60°) ≈ 9.2 metres
🔢 Part 2: Calculations and Problem Solving
5. A tree casts a shadow 12 metres long when the angle of elevation to the sun is 35°. Calculate the height of the tree. Show your working.
Height = _________ metres (round to 1 decimal place)
6. From the top of a 25-metre tall building, the angle of depression to a car is 28°. How far is the car from the base of the building?
Distance = _________ metres (round to 1 decimal place)
7. In triangle ABC, angle C = 90°, side AB = 15 cm, and angle A = 42°. Find the length of side BC (opposite to angle A).
BC = _________ cm (round to 1 decimal place)
8. A wheelchair ramp has a horizontal distance of 6 metres and rises 0.5 metres vertically. What angle does the ramp make with the horizontal?
Angle = _________ degrees (round to 1 decimal place)
💭 Part 3: Reflection and Application
9. Explain in your own words when you would use the sine ratio instead of the cosine ratio.
10. Describe a real-world situation where you might need to use trigonometry. Explain which ratio you would use and why.
11. What challenges did you face when measuring angles and sides in today's practical activity? How did these affect your calculations?
