Question

A line of length 20 cm is placed in profile plane making an angle of 65 degrees with the horizontal. What is the length of line side view?

(a) 18.12 cm

(b) 8.45 cm

(c) 20 cm

(d) 22.06 cm

This question was addressed to me during an interview.

Origin of the question is Line contained by a Plane Perpendicular to Both the Reference Planes topic in chapter Projection of Lines of Engineering Drawing

Answer 1

Right choice is (c) 20 cm

To explain I would say: The view given is side view in this view whatever the angle made by line with any of the other planes except the profile plane it gives the actual length. So here the actual length and side view length become equal.
