You are given a vector in the xy plane that has a magnitude of 95.0 units and a y component of 40.0 units. What are the two possibilities for its x component?

the x component will be + sqrt (95^240^2) according to Pythagoras

how did you get that as the answer though??

and wat is this +sqrt thing mean?

Have you ever heard of Pythagoras and his theorem on right triangles? sqrt means square root.
I am wondering how one does vectors in the Cartesian plane without Pythagoras? Even Rene Descartes used it. 
nvm shes wrong

55, 55 i had my friend help me

plzzzzzzz BOB PURSLEY HELP ME
