1.	A mirror 30 mm X 40 mm is inclined to the wall such that its front view is a square of 30mm side. The longer side of the mirror appear perpendicular to both HP and VP. Find the inclination of the mirror with the wall.(a) 48.76^o(b) 36.78^o(c) 51.76^o(d) 41.41^oThe question was posed to me in quiz.I need to ask this question from Projections of Planes topic in chapter Orthographic Projection, Projections of Lines, Planes and Solids of Civil Engineering Drawing
Answer» The CORRECT option is (d) 41.41^o The BEST I can explain: REFERRING the figure below, on MEASURING the value of φ, inclination is known.
