Let AB = hm be the height of pole and length of rope is 20 m tied from the
Top of tower AB and = 30o
In right Δ ABC, we have
(i) For Children below age of 5 years
Height of slide = 1.5 m
Angle of inclination of slide = 30o
(ii) For Children below age of 5 years
Height of slide = 3m
Angle of inclination of slide = 60o
Draw figure for both cases:
In right Δ ABC, we have
Sin 30o = AB / AC => 1/ 2 = 1.5 /AC [ sin30o =1/2]
AC = 3m
In right Δ DEF, we have
Sin 60o = DE /DF =>
DF =
Draw a figure according to given conditions,
Let AB = x m be the height of transmission tower
BC = 20 m height of building (given)
Angle of elevation from top of tower = 600
Angle of elevation from bottom of tower = 45o
To find : height of tower i.e., AB
Let the height of tower AB = x m
