Homework Statement


Find the x, y, and z components of the vector A shown in the figure , given that A = 65 m.

The Attempt at a Solution



Y Component: 65m*cos(35) = 53.24m

Z Component: 65m*cos(55) = 37.28m

I think these two are right, but I don't have a clue how to solve for the X component.

Your Z component is correct.
The other component 65m*cos(35) the component of A on the x-y plane.
From this component find the x and y components.

Do you think you could give me just a little nudge in the right direction? I can't figure out how to go from here.
 
65m*cos(35) is the component of A on the x-y plane.
This component makes 35 degrees with the x-axis.
Hence its component on x-axis is 65m*cos(35)*cos(35)
and on y-axis is 65m*cos(35)*sin(35)
 
Okay, I understand everything now, thanks so much for the help!
