Answer:Coming out like this the normal vectors are going to be parallel to one another. So it's easier for me to test to see whether the normal vectors are parallel.
This is because mathematics uses some theories that helps to change words to equations. for example, a tree of height 50m makes a shadow on the ground. an observer standing at angle of 30 degrees, calculate the distance of the man to the tree. we use the the formula, tan (30)=opp/adj
