Three displacement vectors A, B, and C  in a plane are specified by their magnitudes A = 10.0 cm, B = 7.0 cm, and C = 8.0 cm, respectively, and by their respective direction angles with the horizontal direction α = 35°, β = −110° , and γ = 30° . The physical units of the magnitudes are centimeters. Resolve the vectors to their scalar components and find the vector sum.
