Pleaaaseee somebody i can't understand it.. i really want to but don't get it.. if i see the steps, i might be able to..

resolve f into components fx and fy if f = 10.0 n and its cartesian angle is −30°.

Fx = 8.66 N

Fy = -5.00 N

Explanation:

Cartesian angle means the angle measured counterclockwise from the +x axis on the Cartesian (xy) plane.

To find the force components of a force with magnitude F and Cartesian angle θ, use trigonometry:

Fx = F cos θ

Fy = F sin θ

Here, F = 10.0 N and θ = -30°.

Fx = 10.0 N cos (-30°) = 8.66 N

Fy = 10.0 N sin (-30°) = -5.00 N

a and c

c is 100% but i am confused in a

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
