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

Dafna11 [192]

The inequality that represents the possible ways nina can eat 12 or more grams of protein is 2x + 3y ≥ 12

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more number and variables.

Let x be the number of cheese squares that she eats and y is the number of turkey slices that she eats. If nina can eat 12 or more grams of protein, hence:

2x + 3y ≥ 12

The inequality that represents the possible ways nina can eat 12 or more grams of protein is 2x + 3y ≥ 12
