The length of the shadow on the ground of a tall tree of height 30m is 10√3m. What is the angle (in degrees) of elevation of the sun?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 60
In△ABC -
Let AB be the tower and BC be its shadow.
tanθ = AB/BC
tanθ = 30/10√3 = √3
tanθ = tan600
θ = 600
