Find the angle between vector u= 3i + sqrt 3j and vector v=-2i-5j to the nearest degree a) 82 degrees b) 38 degrees c) 142 degrees d) 98 degrees

The angle between u and v is 142°

C is correct

Step-by-step explanation:

Given:

We need to find the angle between u and v vector.

Using dot product.

where,

Nearest degree

Hence, The angle between u and v is 142°
