Let g be a group, h a subgroup of g and n be a normal subgroup of g. show that k=c_g(h) ∩ c_g(n) is a normal subgroup of n_g(h) and that the quotient group n_g(h)/k is isomorphic to a subgroup of aut(hn).

answer: no, but if it does it's a obvious pattern.

step-by-step explanation:

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
