- A10(2 + √3) m
- B10√3 m
- C20 m
- D10(1 + √3) m
Step-by-Step Solution
Broken part = 10 ÷ cos 60° = 20 m; standing part = 10 tan 60° = 10√3 m. Total = 20 + 10√3 = 10(2 + √3) m ≈ 37.3 m.
Answer: A) 10(2 + √3) m
A storm snaps a tree. The broken part bends over so that its top touches the ground 10 m from the foot, making an angle of 60° with the ground. How tall was the tree?
