1.

a boy 2m tall is standing at some distance from a 30 m tall building. the angle of elevation from his eyes of the top of the building increases from 30° to 60°. find the distance he walked towards the building.

Answer»

tan 60 =30-2/ab

root 3 =28/ab

ab = 28/root 3

tan 30 = 28/cb

1/root 3 = 28/ ac + 28/rt 3

ac =28 rt 3 - 28/rt 3

ac =84 - 28/rt 3

ac =56/rt 3

32.34m.

Am i right

no u r wrong sonu😑
