France in danger

Geometry Level 2

It has been seen that an alien who is trying to invade France is standing on top of the Eiffel tower. Security armies were called to shoot at the alien. The height of the Eiffel tower is 324 m tall and they have to stay away at least 180 m because the alien can sense it. To prevent this they are going to shoot from a distance of 179 m. 1 m for safety might come in handy ! Calculate the angle of elevation between the ground and the weapon which is pointing at the alien. They only have 3 minutes so solve it fast and help France !!!

$\Rightarrow \!\,$ A diagram to make it easy

$\Rightarrow \!\,$ $\large Tan\ x =\frac {324}{179}$

$\Rightarrow \!\,$ So after solving it you get $\large x = 61$

Is it possible to create diagrams like this using Microsoft software? e.g Power point, word, excel.. paint etc.

I don't think so. I used

This is a free online tool. After completing I usually use "Snipping tool" to crop it off and then save it
