Find the angle between the given vectors to the nearest tenth of a degree.
u = < 6, -1> , v = < 7, -4>

A

Step-by-step explanation:

Given

u = <6, -1>

u = 6i-j

and

v=<7,-4>

v=7i-4j

The formula for angle is:

Let x be the angle

where ||u|| is the length and u.v is the dot product or scalar product of both vectors

So,

The calculated angle will be in radians. To find the angle in degrees:

Hence Option A is correct ..
