I really need help- 3a-2b=19
5a+8b=21

Transform these so that they can eliminate "as"

what should they do?

a

+2a

b

x15

x15

c

x3

x5

d

x5

x3

In each of the cases that follow, the magnitude of a vector is given along with the counterclockwise angle it makes with the +x axis. use trigonometry to find the x and y components of the vector. also, sketch each vector approximately to scale to see if your calculated answers seem reasonable. (a) 50.0 n at 60.0°, (b) 75 m/ s at 5π/ 6 rad, (c) 254 lb at 325°, (d) 69 km at 1.1π rad.
