Find the magnitude and direction angle of the vector a given below. Express your answer to one decimal place.
a=12i−18ja = 12i - 18ja=12i−18j
a=(31i−17j)−(25i−17j)a=(31i-17j)-(25i-17j)a=(31i−17j)−(25i−17j)
For the given vector, calculate its magnitude and direction angle relative to the positive xx-axis. Express your answer to the nearest tenth, if required.
〈−17,−29〉〈-17,-29〉〈−17,−29〉
