But the question is not there
"Two vectors are perpendicular if their dot product is zero, and parallel if their dot"
Answer:
c=18
Step-by-step explanation:
<em>To solve for c you need to do cross product property</em>
You have to multiply diagonally
So 3*30= 90
5*c= 5c
90= 5c
Now its a one step equation
Divide 90 by 5 =18
c= 18
