1) In concave equilateral pentagon ABCDE, Angle A is qual to Angle B is equal to 90 degrees. What is the degree measure of angle E?

2) Alex thinks 131 degrees are neat. What is the maximum number of interior angles of a convex n-gon that can have measure 131 degrees?

I believe we have something like this  :

Angle A  =  B   = 90°   and the pentagon is equilateral

If we connected  EC, triangle  DEC is equilateral.....so angle DEC  = 60°

And angle AEC  =  90°

And angle AED  =  AEC - DEC  =  90°  -  60°   =  30°  =  angle  E

I'm less sure about this one....but.....based on this figure.....I  get  a   max of 6 angles that measure 131°
