Gis the incenter, or point of concurrency, of the angle bisectors of δace.

triangle a c e has point g as its incenter. lines are drawn from the points of the triangle to point g. lines are drawn from point g to the sides of the triangle to form right angles. line segments g b, g d, and g f are formed. angle f e g is (3 n minus 1) degrees and angle d e g is 20 degrees.
what is the value of n?

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
