1. The problem statement, all variables and given/known data On a treasure map, A = -5 (km)x + 2 (km)y, B = 4 km, and theta = 328 deg. The treasure is located at C = 4A - 3B. What is the x-coordinate of the treasure? What is the y-coordinate of the treasure? 2. Relevant equations a^2 + b^2 = c^2 Vector addition 3. The attempt at a solution So to tackle this one I decided that the C couldn't have been making a triangle between the two vectors since C wasn't equal to sqrt(A^2 + B^2). I thought that maybe if I just find 4A in C that would be the x coordinate, and 3B would be the y. I guess that line of logic was wrong, as I didn't get a correct answer. So can someone help? Please also explain, vectors are confusing to me.
