Answer:
The length of the shadow is 3.17 feet .
Step-by-step explanation:
Given as :
The height of the person walking on street = H = 5'6''
∴ 12" = 1 '
So, 6" = × 6 = 0.5'
I.e H = 5.5 feet
The angle of elevation of from tip of shadow to sun = Ф = 60°
Let The length of the shadow = X feet
<u>Now, From figure</u>'
Tan angle =
Or, Tan Ф =
Or, Tan 60° =
Or, Tan 60° =
Or, 1.732 =
Or, X =
∴ X = 3.17 feet
So, The length of the shadow = X = 3.17 feet
Hence, The length of the shadow is 3.17 feet . Answer
