Hi! I reallyreallyreally need ur help with this. ex.1 To find the vertical and horizontal components of the force mg, I need to use the given angle [itex]\beta[/itex]. The problem is I dont know how to use it. I have tried to use the corresponding angles postulate. But I cant make it to work. How should I think to find the components? ex2. Its the same thing here. I dont know how to think so I can use the given angle [itex]\beta[/itex] to calculate the components of mg. Im sorry for my bad english but I hope you will understand what I want to ask. Thanks!
