<h2>Angle did the helicopter take off from is 11.31°</h2>

Step-by-step explanation:

Refer the given figure.

The initial position of helicopter is A.

It needs to go to position C.

We need to find angle A.

We have

          tanA=\frac{BC}{AB}\\\\tanA=\frac{160}{800}\\\\A=11.31^0

Angle did the helicopter take off from is 11.31°

Step-by-step explanation:

2 right triangles are formed.

x is the angle btw wire and grnd

tan x = 10/5 = 2

tanx = ht of tower/(5+14)

2 = tower ht/19

tower ht = 38

length of wire =

\sqrt{ {38}^{2} +  {19}^{2}  }

AveGali [126]

Answer:

    The career planning process is ongoing and sequential. Since it is fluid rather than chronological, you move to the next step only when you are ready to do so, and you may move back and forth between steps at any given time. The career planning process is also cyclic. When career change is desired anytime during your work life, you may repeat the process once again. Data from the U.S. Bureau of Labor Statistics indicates that the majority of members of the labor force will make three to four major changes in their career during their 35 to 45 years of working. Because human beings are complex, each of us has unique aspirations, goals, potential for development, and limitations. Although we can follow the same process, career planning outcomes must be individualized.
