Thanks so much! I should have thought of the pythagorean therom, but why x^2=70^2-55^2 rather than x^2+(-55^2)=70^2?

You are given a vector in the xy plane that has a magnitude of 70.0 units and a y component of -55.0 units. What are the two possibilites for its x component? Please explain, thanks! :)
physics
using the kinematic equation: displacement=initial velocity*time+ .5(acceleration*time^2) delta x= 0*7.8+.5(2.3*7.8^2) delta x= .5(2.3*7.8^2) delta x= .5(2.3*60.84) delta x= 69.966 m with sig figs your answer would be 70 m hope this helps!
