Question

If a towere 30 metre high casts a shadow 10 metre long on the ground then what is the angle of elevation of the Sun

Answer 1

hey...your answer:-

Let theta be the angle of elevation of sun. tan theta = height of tower ÷ length of shadow

in this case tan theta = 30/10√3 = √3

since tan theta is √3 the theta is 60 degrees

therefore the angle of elevation is 60 degrees.

hope this will help u

Answer 2

Answer:

Angle of elevation of the sun= 30

Explanation:

Let ∅ be the angle of the sun from the shadow

Then,

tan∅ = Height of the shadow / Height of the tower

⇒tan∅= 10/30

⇒tan∅=1/3=tan30

⇒∅=30
