During daytime on Mars the planet's surface becomes warm because the sun's energy gets transferred across space to the planet. This heat transfer
is accomplished primarily through what means? *

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
