Q.	The length of line placed in profile plane and making an angle of 30 degrees with the vertical is 5 cm from front view. What is the actual length?
A.	5 cm
B.	8.66 cm
C.	10 cm
D.	5.77 cm
Answer» D. 5.77 cm
Explanation: the length of line making an angle with vertical if viewed from front view the length will be the product of length of line cosine of angle given. l * cosine (30) =5 cm, x= 5/ cosine (30)= 5.77 cm.
