Question

Find the length of the shadow of 10m high tree if the angle of elevation of the sun is 30degree

Answer 1

Answer:

17.32 m

Step-by-step explanation:

let height of shadow is 'h'

tan 30°= 10/h

1/√3= 10/h

h=10√3

h=17.32 m

Answer 2

Dear Student,

● Answer -

Length of shadow of the tree = 20 m

● Explanation -

# Given -

h = 10 m

θ = 30°

# Solution -

Let x be length of the shadow.

In this arrangement, we have -

sinθ = h / x

x = h / sinθ

Substitute values,

x = 10 / sin30°

x = 10 / 0.5

x = 20 m

Hence, the length of the shadow of 10m high tree is 20 m.

Thanks dear. Hope this helps you...
