Can any one explain how to look for d direction of a vector .​

The direction of a vector is the measure of the angle it makes with a horizontal line . tanθ=y2 − y1x2 − x1 , where (x1,y1) is the initial point and (x2,y2) is the terminal point. Example 2: Find the direction of the vector →PQ whose initial point P is at (2,3) and end point is at Q is at (5,8)

the first question mark is 6 and the second question mark is 26 (the square root)

step-by-step explanation:

∞ this is your sign
