What are the x and y components of a vector a with arrow in the xy plane if its direction is 170° counterclockwise from the positive direction of the x axis and its magnitude is 8.8 m?

The rectangular coordinates of polar vector (r, θ) are (r·cos(θ), r·sin(θ)). For your (r, θ) = (8.8, 170°), the rectangular coordinates are

... (8.8·cos(170°), 8.8·sin(170°)) ≈ (-8.666, 1.528)

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10
