The magnitude of vector b is 47 units

<h3>Further explanation</h3>
Vector is quantity that has magnitude and direction.
One example of a vector is displacement.
Let us now tackle the problem !

This problem is about Vector Diagram.
<em>Assume :</em>
<em>Unit vector in the positive y-direction are </em>
<em>Unit vector in the negative y-direction are </em>

<em>Vector
has a magnitude of 29 units and points in the positive y-direction :</em>
→ <em>Equation 1</em>

<em>The resultant vector
+ vector
points in the negative y-direction with a magnitude of 18 units :</em>

← <em>Equation 1</em>



<h3>Conclusion :</h3>
Magnitude of vector
is 47 units
