What is the angle between v=(-7,8) and w=(5,3) 1) use the formula v1*v2=|v1||v2|cos(theta) to find the cosine of the angle between these vectors. 2)use the cosine of the angle to find the actual angle between the two vectors.

Step-by-step explanation:

vector v is -7i+8j

vector w is 5i+3j

Angle between vectors is given by

therefore applying above formula

-35+24=

side side side

side angle angle

angle side angle

side angle side

step-by-step explanation:
