Question

If the length of a shadow cast by a pole be √3 times the length of the pole,find the angle of elevation of the sun?

Answer 1

Angle of elevation by sun = 30

explanation:-
Let the length of the pole be 'x'
the length of a shadow cast by a pole = 3x
Angle of elevation by sun 'A'

by trigonometry
TanA = P/B
TanA = x/√3x
TanA = 1/√3
(From trigonometry table)
TanA = Tan30.
A = 30

Angle of elevation by sun = 30

Answer 2

Answer:

Step-by-step explanation:

explanation:-

Let the length of the pole be 'x'

the length of a shadow cast by a pole = 3x

Angle of elevation by sun 'A'

by trigonometry

TanA = P/B

TanA = x/√3x

TanA = 1/√3

(From trigonometry table)

TanA = Tan30.

A = 30

Angle of elevation by sun = 30
