For the vectors shown below, determine the values of A and the acute angle 2 (in degrees) that would make v1+Av2=5i7j. Use that 1=20o, v1=2 and v2=3....

For the vectors shown below, determine the values of A and the acute angle 2 (in degrees) that would make v1+Av2=−5i−7j. Use that 1=20o, v1=2 and v2=3.
