Hello, NIKITA!

Did you make some sketches?

Code:

T *
| * *
| * *
| * *
| * *
| 24° * *
* - - - - - * - - - - - *
O 85 A 40 B

In right triangle

Therefore: .

2) The distance

3) The angle of elevation of from to the nearest degree. In

Therefore: .

4) The distance Code:

T *
| *
| *
38 | *
| *
| 18° *
* - - - - - - - - - - - *
O C

In

Therefore: .

5) The distance

In

Therefore: .

6) The distance Looking straight down at the ground, we have: Code:

85
O * - - - - - - - - * A
* |
* |
117 * |
* |
* |
* C

From Pythagorus: .

Therefore: .

7) Calculate the bearing of from , nearest degree. Again, looking straight down at the ground . . .

Code:

40
A * - - - - - - - - * B
| *
| *
80 | *
| θ *
| *
*
C

We have: .

Therefore: .
