Question 1
What is the vertical reach (BD) if the pole is 5 m tall and the repair point is 1.3 m below?
π‘ Hint: Think about the height above and below the point required.
Question 2
When the ladder is inclined at 60 degrees, how can BC (the length of the ladder) be determined?
π‘ Hint: Recall the relationship between opposite sides and the hypotenuse.

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?
π‘ 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?
π‘ Hint: Cotangent helps give us the adjacent side from the known vertical height.
