Using the diagram, what is the intersection of plane abcd and ? a. line b. point c c. plane efgh d. point d

I have attached screenshots for the complete question as well as the diagram associated with it.

point C

Explanation:
A plane and a line can either:
1- have no intersection
2- intersect in a point
3- intersect in a line in case the whole line is found in this plane

For the given:
We can see that line CG does not belong to the plane ABCD, however, they both intersect.
This means that the intersection between them is a point.
We can note that the only point common between the line and the plane is point C.
Therefore, plane ABCD intersects line GC at point C

Hope this helps :)

Did u want to find the value of x?
