[Solved] A line of length X cm lied on horizontal plane turned 60 degrees with respect to horizontal plane by keeping one of its ends fixed and attained length of Y cm top view. Which of the following statement is true?

Q.	A line of length X cm lied on horizontal plane turned 60 degrees with respect to horizontal plane by keeping one of its ends fixed and attained length of Y cm top view. Which of the following statement is true?
A.	x =y
B.	x=2 * y
C.	x= ½ * y
D.	x >y
Answer» C. x= ½ * y
Explanation: as cos (60) =0.5. the x would equal to ½ *y. the relation would be like this. x=y happens if we watch from front view. and x will not be greater than y as x is made to turn either it would stay same or become less than it.
