Let v1=(1, 6) and v2=(5, -3)

(a) compute v1+v2, v1-v2, and v2-v1.

(b) sketch v1, v2, v1+v2, v1-v2, and v2-v1 on the axes below.

See Explanation;

Step-by-step explanation:

The given vectors are;

and

a) To add or subtract two vectors, we add or subtract their corresponding components

b) See attachment for graphs(1,6

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
