When two parallel lines are cut by a transversal, the two pairs of angles on opposite sides of the transversal and outside the parallel lines, and the angles in each pair are congruent.
Both alternate interior and alternate exterior angle pairs lie on opposite sides of the transversal.
Pairs of Alternate Exterior Angle are Congruent

It is the alternate angle to the angle of elevation

The answer depends totally on how the angles are numbered. And since you have not bothered to provide that information, I cannot provide a sensible answer.
Exterior angle+interior angle=180 degrees and 180-exterior angle=interior angle
If you mean a regular pentagon then each interior angle is 108 degrees and each exterior angle is 72 degrees
If you mean exterior angle is twice its interior angle then an equilateral triangle will fit the given description because each interior angle is 60 degrees and each exterior angle is 120 degrees
It is: 180-interior angle = exterior angle
