Question 1

What is the vertical reach (BD) if the pole is 5 m tall and the repair point is 1.3 m below?

  • 4.3 m
  • 3.7 m
  • 5.1 m

πŸ’‘ Hint: Think about the height above and below the point required.

Challenge Problems

Push your limits with challenges.

Question 1

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 50Β° angle?

πŸ’‘ Hint: Remember to use the sine function with the new angle.

Question 2

If the angle is adjusted to 30Β°, what would be the new distance from the pole if the vertical height required remains the same?

πŸ’‘ Hint: Cotangent helps give us the adjacent side from the known vertical height.
