A tree breaks due to storm and the broken part bends so that the top of the tree touches theground where it makes an angle 30° The distance between the foot of the tree to the pointwhere the top touches the ground is 8 m. Find the height of the tree from where it is broken. |

Answer» Answer: Answer is 8 root 3 Step-by-step explanation: Let AC is the tree which break at B, and the broken PART AB become BD. In triangle BCD, BC / 8 = 1 / root 3 BC = 8 / root 3 Similarly, DC / BD = cos 30 8 / BD = root 3 / 2 BD = 16 / root 3 Therefore, height of the tree => AC = AB + BC = 16 / root 3 + 8 / root 3 = 24 / root 3 On rationalize => 24 root 3 / 3 Which means the answer will be 8 root 3 If it is helpful for you then mark me branliest ALSO thanks my anwers and follow.. |
