I'm taking an engineering intro class, and this problem has me stuck:
"Vector R in Fig. 4.9 is the difference between vectors T and S. If S is inclined at 28 degrees from the vertical and the angle between S and T is 32 degrees, calculate the magnitude and direction of vector R. The magnitude of S and T are 19 cm and 36 cm, respectively. " Fig. 4.9 Is simply three lines pointing diagonally downward from the top right, with R being horizotal, T below R, and S below T (sorry, I cant find a picture to upload). I only have pre-calc under my belt (no physics) but I feel like this shouldn't be to hard to understand. I'm just finding it impossible to figure out HOW to solve this. I have access to the answer:(R = 18.8 cms, direction is horizontal) but I really need to know how to do it. Any help is greatly appreciated. Thanks
