Question 536855
I'm not sure how to figure this out.. Can you help me & explain how I would solve?

I cannot tell from what you wrote whether the figure is like this:

{{{drawing(400,400,-1,11,-3,9, line(0,0,10,0),
locate(0,0,O), locate(10,0+.5,R), locate(9.9,1+.7,S),locate(6.7,7.9,T), 
line(9.923639667,1.233513028,0,0), line(6.664746415,7.455277005,0,0) )}}}

in which case we would subtract m&#8736;ROS =  7ｰ5'8" from +m&#8736;ROT = 48ｰ12'16"

  
 m&#8736;ROT = 48ｰ12'16"
-m&#8736;ROS =  7ｰ 5' 8" 
覧覧覧覧覧覧覧覧覧覧覧覧
 m&#8736;SOT   41ｰ 7' 8"

or whether it's like this:

{{{drawing(400,400,-1,11,-3,9, line(0,0,10,0),
locate(0,0,O), locate(10,0+.5,R), locate(10.1,-1.1,S),locate(6.7,7.9,T), 
line(9.923639667,-1.233513028,0,0), line(6.664746415,7.455277005,0,0) )}}}


in which case we would add them:

 m&#8736;ROT = 48ｰ12'16"
+m&#8736;ROS =  7ｰ 5' 8" 
覧覧覧覧覧覧覧覧覧覧覧覧
 m&#8736;SOT   56ｰ17'24"
