The measure of the vertex angle of an isosceles triangle is 92. find the measure of a base angle
the sum of the angles in a triangle = 180°
in an isosceles triangle the base angles are equal, thus
base angle = = = 44°
f(x) is undefined at x=0.
the domain of f does not contain 0.
x ! = 0.
the domain of g is unrestricted, reals or complexes.
