<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°
