I need help with Using components to find the answers and checking with the diagrams

#3. [Vectors] Two vectors are given by A = 8.0i + 6.0? and f3 = 5.0'i — 12.0? (a) Draw each vector carefully on a scale diagram with x—y axes. Use components find the
angle (in 0) each vector makes with the --x—axis. Check these with your diagram. (b) Carefully construct the vectors A —- fl and I} — Eon your diagram. Use the components
of A and 1—3 to calculate vectors A + E and I? u; , and show that these results agree with the
drawings on your diagram. (c) Calculate the value of A o f! directly using the components of these vectors. Then use this
result to find the angle between the two vectors without using your results from (a). Show that

We find that the angle A makes with the positive x-axis is 36.87, and... View the full answer
