For triangle ABC, angle A = x + 30, angle B =2 x - 4, and angle C =4x. If triangle ABC undergoes a dilation by a scale factor of 1/2 to create triangle A'B'C with angle A =2x + 8 , angle B = x + 18, and angle C = 5 x - 22 , which confirms that triangle ABC and triangle A'B'C by the AA criterion

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°
