In a plane line b is parallel to line f, line f is parallel to line g, and line h is perpendicular to line b, which can not be true

Answer with explanation:

It is given that , in a Plane

→  Line B ║ Line F

→  Line G ║ Line F

Two lines parallel to the same line are parallel to each other.

⇒ Line G ║ Line F ║Line B

If there are two or more parallel lines in a plane, and a line is perpendicular to either any of the parallel lines, then that line is perpendicular to all the parallel lines.

→Also,it is given that,  Line H  ⊥  Line B.

∴Line H  ⊥  Line F.

∴Line H  ⊥  Line G.

⇒Line H can not be parallel to , line G or line F.

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
