The point \(A\) is
located \(20\, \mathrm{cm}\) from a
mirror and the point \(B\)
is located \(50\, \mathrm{cm}\)
from the same mirror. The direct distance between
\(A\) and
\(B\) (the length of
the segment \(AB\))
is \(70\, \mathrm{cm}\).
Find the angle of incidence of the ray through the point
\(A\) which is reflected
to the point \(B\)
and round your answer to nearest degrees. (The angle of incidence is the angle
between the incident ray and the normal to the mirror.)
