Answer:

10.58 N

Step-by-step explanation:

Let us find component of these forces in x and y direction.

The solution along with diagram can be found in attachment.

We have found resultant in X- direction = 6√3 N

resultant in Y- direction = 2 N

therefore net force resultant force = \sqrt{(6\sqrt3)^2+2^2}

= 10.58 N

Svetlanka [38]

Given:

The side of a square is,

(s+3)inches

Required:

To find the perimeter of a given square.

Explanation:

Therefore, all sides are (s+3).

To find perimeter, we need to add all the sides,

Therefore,

\begin{gathered} (s+3)+(s+3)+(s+3)+(s+3) \\ =4(s+3) \end{gathered}

Final Answer:

Option (d) is correct.
