Adog pulls on a pillow with a force of 8.4 n at an angle of 31 degrees above the horizontal. what is the x component of this force?

0.863333

86%

hope this

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
