Using the magnitudes of vector = 23 units, and vector rightwards arrow for b of = 12 units given in question 8, find the magnitude and direction of the vector sum rightwards arrow for S of using the formulas: s space equals space square root of a squared plus b squared end root = theta equals tan to the power of negative 1 end exponent open parentheses b over a close parentheses Compare these values with those obtained in question 8. Are these formulas appropriate to calculate the resultant of two vectors (magnitude and direction)? Use the editor to format your answer
