Slope of line l (m1)=5
Slope of line w(m2)=-1/5
Since,m1×m2=-1 , line 'l' and 'w' are perpendicular.
Since line 'k' doesn't intersect line 'l' ,they must be parallel b'coz they are in the same plane as well.
Here, 'l' is perpendicular to 'w' and parallel to 'k'....so w and k must be perpendicular to each other.
It can be proven:
Since l and k are parallel, their slopes are equal.
So, slope of k (m3)=5
Since m3×m2=-1 ,w and k are perpendicular.
Hence, angle between w and k is 90°
Answer:
$24
Step-by-step explanation:
What do we know? 3 toy cars cost a total of $2.88. $2.88 divided by 3 gives us $0.96 per car. If it is $0.96 per car and there are 25 cars, that gives us a total of $24 for 25 cars.
