Answer» HI, Here is your answer Given: Distance=8√3m Angle made=30° To Find: Height when it is bent=AB The total height=AB+AC Solution: From triangle ABC tan 30=Opposite/Adjacent tan 30=x/8√3 x=8m Therefore AB=8m By PYTHAGORAS theorem AC²=AB²+BC² AC²=64+192 AC=√256 AC=16m Hence Height of the pole when it is bent=8m Total height=AB+AC=8+16=24m Hope this helps you. |
