hope it helps
follow me✌
Step-by-step explanation:
Let AB be the original height of the tree.
Suppose it got bent at a point C and let the
part CB take the position CD, meeting the ground at D. Then,
→ AD = 8m, ADC = 30° and CD = CB.
→ Let AC = x metres and CD = CB = y metres.
From right ∆DAC, we have
=>
=>
=> x =
=> x =
=> x =
▶ Also, from right ∆DAC, we have
=>
=>
=> y =
=> y =
=> y =
▶ Total height of tree = AC + BC.
✔✔ Hence, it is solved ✅✅.
