Those are the same questions?

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Re: Help with 2 questions

measure of an angle is generally not in radical form
O.K.let us be specific.
Let ABCDEFGA be the heptagon. A diagonal AD divides it into a pentagon and a quadrilateral. Now tell us which is the angle which you want to calculate?
