I have a problem where i have found the angle for one line but i cant find the angle for the other. See attached picture i couldn't find how to add the picture to the post without a url for it. so far i have the x and y values for two line im only missing the third line.
f1 = 1570 lb ^x 0 lb ^y
f2 = 532 lb ^x 1740 ^y i got 17 degrees as an angle for this line
