an airplane flying due north 90 km/h is being blown due west at 50 km/h. what is the resultant velocity of the plane?

I'm having some difficulty seeing the diagram clearly.but the question says there's a net inward force on the object.so we know right away,  from newton's 2nd law of motion, thatthat baby is accelerating.  it doesn't even matter which way thenet force is pointing.  if there's any net force, then either theobject's speed or else its direction must be changing.

Athermometer to measure the temperature of course 

Sertghjnbfdsad oh and me too

Assuming you're referring to significant figures, none of these answer choices are shown to be zero as significant digits. did you, by chance, forget to add something?
