Answer :

Let BC be height of the tree.

AB be the breadth of the river.


A be the initial position of the person


D be the final position of the person


CAB = 60° & CDB = 30° & DA = 40m


Let AB = x & BC = h



In Δ DBC




……. (1)


In Δ ABC




…… (2)


Using (1) & (2)







AB = 20m


BC =20√3 m =20×1.73 =34.6m


Height of the tree is 34.6m and width of the river is 20m.
