Question

If v1 = (2,5) and V2 = (4,-3), then the angle between the two vectors is

Round your answer to two decimal places,

Answer 1

105.07°

Explanation:

The angle of v1 is ...

arctan(5/2) ≈ 68.199°

The angle of v2 is ...

arctan(-3/4) ≈ -38.870°

The angle difference between the two vectors is ...

68.199° -(-38.870°) = 105.07°
