1.a point

assume book be the plane and pen be the line

now keep the pen in different directions except not on the book you will get that

2.do you mean A,B,C are in the same line if yes answer is 15

AB+BC=AC if they lie on same line

so remaining length BC is 15 hope this is clear

3.. same as above

AB+BC=AC

6x=42 so x=8

4..calculate x as above you get x=7

so BC=2*7 +4 =18
