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

It’s means the average. Combine all numbers then divide by the total numbers you have.
Answer:
d ≤3
Step-by-step explanation:
9−4d≥−3
Subtract 9 from each side
9-9−4d≥−3-9
−4d≥−12
Divide by -4, remembering to flip the inequality
-4d/-4 ≤ -12/-4
d ≤3
