Q.	The length of line placed in profile plane from front view is product of actual length and (angle with horizontal plane).
A.	cosine
B.	sine
C.	tangent
D.	secant
Answer» B. sine
Explanation: as the angle is between the line and horizontal plane the height is the length of the line in front view. if angle with vertical is given the length will be product of actual length and cosine of angle between the line and vertical plane.
