Lostsunrise [7]

The mean is the average you’re used to see by adding up all numbers and divide by all the number of the numbers. The median is the middle value in the list of numbers the mode is the value that occurs most often. If no number in the list is repeated then there is no mode for the list

A helicopter is hovering 450 feet above the ground. The angle of elevation

SIZIF [17.4K]

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 = $\dfrac{\textrm Perendicular}{\textrm Hypotenuse}$

∴ Sin 56° = $\dfrac{\textrm h}{\textrm x}$

Or, 0.8290 = $\dfrac{\textrm 450}{\textrm x}$

Or , x = $\dfrac{\textrm 450}{\textrm 0.8290}$

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

Area of the triangle =[6 x (6√3) /2 ] / 2 ===>9√3=15.588

Area of each sector : (π/6). r² = π/6 x 9===.>4.712
And for the 3 sectors 3 x 4.712 =14.137
The shaded area is

15.588 - 14.137= 1.451
