Answer 1

A_x = A cos alpha = 8.19 A_y = A sin alpha = 10 times sin (35 degree) = 5.74 B_x = B sin 20 degree (- i^) = 7 times sin 20 degree = -2.39 i^ B_y = B cos 20 degree (- j^) = -6.58 j^ B_x = -2039, B_y = -6.58 C_x = A_x + B_x = 5.8 C_y = A_y + B_y = -0.84 C = squareroot C_x^2 + C_y^2 = squareroot 33.64 + 0.7056 C = 5.86
