Janelle says that lines l and m are skew lines. Planes B and A intersect. Plane B is vertical and contains vertical line n. Plane A is horizontal and contains horizontal line m. Line m and n are perpendicular. Line l is on plane A and it is slightly diagonal.
Is Janelle correct?

Hello.

Step-by-step explanation: Skew lines are those lines which neither intersect nor are in same plane.Here it is given that lines are not parallel so a condition of skew lines is satisfied but it never means that it is proved that they are skew lines.here the lines intersect and are in same plane . So if jenelle says that the lines are skew lines then she is wrong because skew lines never intersect nor are in same plane.

answer is C

Step-by-step explanation:

after simplifying it i got: -36.25 as my answer. hope that !
