Question

At a particular time,the length of the shadow of qutubminar whose height is 72m is 80 m . What will be theheight of an electric pole, the length of whose shadow at the same time is 1000 cm?

Answer 1

hey mate... good morning!

let the height of the electric pole be x m

here shadow of the electric pile is 1000 cm

we know,

1 m= 100 cm

x' = 1000cm

therefore,

shadow of electric pole is 10 m.... (1)

now,

let's assume that the electric pole and qutubminar are parallel to each other and perpendicular time the ground .therefore, both of them firm right angled triangles.

now,

72/80= x/10.......(proportional sides of triangles corresponding each other)

therefore,

72×10=80x

72×10=x

80

now,

9 m= x.

Therefore, the height of the electric pole is 9m
