Transcribed Image Text:Three vectors a, b, and, each have a magnitude of 42.0 m and lie in an xy plane. Their
directions relative to the positive direction of the x axis are 26.0°, 195°, and 313 °,
respectively. What are (a) the magnitude and (b) the angle of the vector a + b + 7 (relative
to the +x direction in the range of (-180°, 180°)), and (c) the magnitude and (d) the angle of
à - b + in the range of (-180°, 180°)? What are (e) the magnitude and (f) the angle (in the
range of (-180°, 180°)) of a fourth vector a such that (a + b) - (7 + d)
=
