We need to find Distance the ball travelled after hitting the tree Given that, After hitting the tree, ball flew towards him i.e we need to find FA Now, FA = GB = CB – CG = 80 − CG ∴ We need to find CG In right angle triangle FCG tan C = (𝑆𝑖𝑑𝑒 𝑜𝑝𝑝𝑜𝑠𝑖𝑡𝑒 𝑡𝑜 𝑎𝑛𝑔𝑙𝑒" " 𝐶)/(𝑆𝑖𝑑𝑒 𝑎𝑑𝑗𝑎𝑐𝑒𝑛𝑡 𝑡𝑜 𝑎𝑛𝑔𝑙𝑒" " 𝐶) tan C = (" " 𝐹𝐺)/𝐶𝐺 tan 60° = 80/𝐶𝐺 √3 = 80/𝐶𝐺 CG = 𝟖𝟎/√𝟑 m Thus, GB = CB – CG = 80 − 𝟖𝟎/√𝟑 = 80(1 − 𝟏/√𝟑) m
