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 βˆ’ CG ∴ We need to find CG In right angle triangle FCG tan C = (𝑆𝑖𝑑𝑒 π‘œπ‘π‘π‘œπ‘ π‘–π‘‘π‘’ π‘‘π‘œ π‘Žπ‘›π‘”π‘™π‘’" " 𝐢)/(𝑆𝑖𝑑𝑒 π‘Žπ‘‘π‘—π‘Žπ‘π‘’π‘›π‘‘ π‘‘π‘œ π‘Žπ‘›π‘”π‘™π‘’" " 𝐢) tan C = (" " 𝐹𝐺)/𝐢𝐺 tan 60Β° = 80/𝐢𝐺 √3 = 80/𝐢𝐺 CG = πŸ–πŸŽ/βˆšπŸ‘ m Thus, GB = CB – CG = 80 βˆ’ πŸ–πŸŽ/βˆšπŸ‘ = 80(1 βˆ’ 𝟏/βˆšπŸ‘) m
