Answer:
A) 63.43°
Step-by-step explanation:
The two vectors in polar form are ...
u = (√(9²+6²))∠arctan(-6/9) = √117∠-33.69°
v = (√(7²+4²))∠arctan(4/7) = √65∠29.74°
The angle between the two vectors is ...
29.74° -(-33.69°) = 63.49°
This should make it more clear! I tried to make it as clear as possible but please let me know if something is blurry or unclear!
I believe the correct answer is the third one. Hope this helped!
