Option B. 20 pieces

Step-by-step explanation:

The length of a strip of wood  = 78 inches

This strip of wood is to be cut into pieces = inches

We have to calculate how many pieces can be cut.

So first we convert mixed fraction to proper fraction and then to decimal.

=   = 3.75 inches

Now we divide 78 inches to 3.75 inches.

78 ÷ 3.75 = 20.8 pieces

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°
