Well to find the area, you simply need to find the formulas! Sadly it specifically depends on the shape alothough that’s what googled for! Just look up the formulas and plug in the legnth width and height maybe even perimeter of base! There you have it!
Answer:90
Step-by-step explanation:
The angle from which helicopter take off approximately equals 11.30993247;
Explanation
We must the tangent line at x = 3 of the function:

The tangent line is given by:

Where:
• m is the slope of the tangent line of f(x) at x = h,
,
• k = f(h) is the value of the function at x = h.
In this case, we have h = 3.
1) First, we compute the derivative of f(x):

2) By evaluating the result of f'(x) at x = h = 3, we get:

3) The value of k is:

4) Replacing the values of m, h and k in the general equation of the tangent line, we get:

Plotting the function f(x) and the tangent line we verify that our result is correct:
Answer
The equation of the tangent line to f(x) and x = 3 is:
