If the lengths of the diagonals of a rhombus are 16 and 18 find the perimeter. round your answer to the nearest two decimal places.

The easiest way to figure out the friction force in the problem is to get the force acting on the vertical. As the plane makes an inclination, vertical force will act on the wood to slide. Therefore, the friction force must be equal to the vertical force in order for the wood not to slide. We will use F = Wx sin ∅.

F = friction force

W = weight of an object

∅ = inclination angle made from the horizontal

18 lbs = 8.165 kg

F = (m)(a)(sin∅)

F = 8.165 x 9.8 x sin 60

F = 69.29 N ≈   69 N  (answer)

Step-by-step explanation:

inch

step-by-step explanation:

yard and mile are too big.

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°
