[Solved] A line parallel to profile plane is held at 30 degrees with horizontal plane and front view gives 2 cm of length. What is the true length of line?

Q.	A line parallel to profile plane is held at 30 degrees with horizontal plane and front view gives 2 cm of length. What is the true length of line?
A.	1 cm
B.	1.73 cm
C.	2.3 cm
D.	4 cm
Answer» D. 4 cm
Explanation: true length of line parallel to profile plane and making angle with horizontal can be of two values either from top view or front view but from side view the length will be given length. as here it is given front view l= 2/sin (30).
