Interactive Quizzes
Quick quizzes to reinforce your learning
What is the vertical reach (BD) if the pole is 5 m tall and the repair point is 1.3 m below?
💡 Hint: Think about the height above and below the point required.
When the ladder is inclined at 60 degrees, how can BC (the length of the ladder) be determined?
💡 Hint: Recall the relationship between opposite sides and the hypotenuse.

Challenge Problems
Push your limits with advanced challenges
An electrician needs to reach a point 2 m below the top of a 7 m pole. What length of the ladder is required if positioned at a 50° angle?
💡 Hint: Remember to use the sine function with the new angle.
If the angle is adjusted to 30°, what would be the new distance from the pole if the vertical height required remains the same?
💡 Hint: Cotangent helps give us the adjacent side from the known vertical height.
