...Hello, im stuck on finding the angles in the following triangle in order to find the resultant forces.
I have this traingle;
which i want to find out all the angles for. I know that the following is;
Rx = 153.2
Ry = 128.56
Here is the angles my teacher found... somehow;
ive tried using the cosine rule, in combination with the resultant x and y forces, but it didnt work
