Q.	A line of length 20 cm lies on profile plane whose ends are at a distance of 5 cm and 7 cm to horizontal plane. What is the length in top view?
A.	7
B.	14.8
C.	15
D.	2
Answer» B. 14.8
Explanation: given the line is of length 20 cm present on profile plane and ends are at 5 and 7 cm away from horizontal plane at right angles. as we imagine the projection planes we can get the top view and distance relation as given here. √(202-(7-5)2 )= 14.8 cm.
