Answer:
The distance of helicopter from the injured person is 542.82 feet
Step-by-step explanation:
Given as :
The height of the hovering helicopter above the ground = h = 450 feet
The angle of elevation from injured person to helicopter = Ф = 56°
Or, Let the distance of of helicopter from person = x feet
Now, From Triangle
∵ Sin Ф =
∴ Sin 56° =
Or, 0.8290 =
Or , x =
I.e x = 542.82 feet
So, The distance from injured person to helicopter = 542.82 feet
Hence The distance of helicopter from the injured person is 542.82 feet Answer
5=x
x=4
didn’t know if u needed work but here
Length is increased so the new length would be 1.1L
The width is decreased by p percent, which now becomes 1-P/100
The new area = 1.1l x (1-P/100)
The area decreases by 12 percent, so the new area = 0.88A
Noe you have 0.88A = 1.1L * (1-P/100)
Simplify to get 0.8 = 1-P/100
Solve for P to get 0.2
Multiply by 100 for the percent: 20%
The answer is C.
