    Angle of vevtor in component form

    No my 294^\circ was the final answer and what was being asked. Yes, 65^\circ turned out to be correct but I don't understand why. Since the question asked: Find \theta_A degrees below the positive x-axis. I thought it would be -65^\circ or 294^\circ By the way are links to a non-copyrighted...

    Angle of vevtor in component form

    Angle of vector in component form Find the vector's magnitude and direction. Use right as the +x direction and up as the +y direction. \vec{A} = 3.50 \hat{i} - 7.70 \hat{j} Find \theta_A degrees below the positive x-axis. \theta_A = arctan\left ( \frac{7.70}{3.50} \right )...
