**Give an example of how trigonometry can or has been used by you in order to solve an actual real life problem. Finally, share an internet source that you have found to be helpful in understanding mathematics.**

There are several applications of trigonometry in real life, one of them calculating the height of a mountain thus knowing the altitude and many other things. Doing this involves knowing the elevation from the point of view and also the distance between its center and where you are taking your measurements. Distance can be taken from the sides then taken perpendicular on the left from the side thus taking the radius conveniently. Now you have the elevation and the base if represented on a triangle.

Use Tan θ=opp/adj

Adj = apposite/tan θ

Adj is the height of the mountain.
