2610/10730 × 100% ≈ 24.324% ≈ 24%
Height of the flagpole before it broke was 32 m
Step-by-step explanation:
- Step 1: This forms a right angled triangle with height 7 m and base 24 m. Find the hypotenuse using the Pythagoras Theorem.
Hypotenuse² = Base² + Height²
= 24² + 7² = 576 + 49 = 625
∴ Hypotenuse = √625 = 25 m
- Step 2: Find the height of the flagpole before it broke.
Since the stuck 7 m and the remaining part which is the hypotenuse together make the flagpole.
⇒ Height = 7 m + 25 m = 32 m
