Vector a⃗ points in the negative x direction. vector b⃗ points at an angle of 30.0∘ above the positive x axis. vector c⃗ has a magnitude of 19m and points in a direction 37.0∘ below the positive x axis.

given that a⃗ +b⃗ +c⃗ =0, find the magnitudes of a⃗ and b⃗ .

Which of the following transformations will make coincide with ? a. counter-clockwise rotation 90º about a, followed by a translation 5 units to the right b. translation 5 units to the right, followed by a reflection across the y-axis c. translation 5 units to the right, followed by a reflection across the x-axis d. translation 1 unit up and 5 units to the right, followed by a reflection across the x-axis
