[Solved] A line AB of length 20 cm is placed in 1st quadrant and parallel to profile plane and the end A and B are 15, 10 cm away from the horizontal plane respectively. The length of the line in the top view is cm.

Q.	A line AB of length 20 cm is placed in 1st quadrant and parallel to profile plane and the end A and B are 15, 10 cm away from the horizontal plane respectively. The length of the line in the top view is cm.
A.	11.18
B.	13.2
C.	17.32
D.	19.36
Answer» D. 19.36
Explanation: the distance between the projectors drawn from a and b to horizontal plane gives the length of line in top view given the line parallel to profile plane. the difference in distances from a and b to horizontal plane is 5 (15-10). given length is
