B

Step-by-step explanation:

The sum of the measures of the angles of a quadrilateral is 360, not 180

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°
