Answer:
108° and 72°
Step-by-step explanation:
let one angle be x then the other angle is x
the sum of the 2 angles = 180°, hence
x + x = 180 ( combining the left side )
x = 180
multiply both sides by 3 then divide both sides by 5
5x = 540 ⇒ x = 108
the 2 angles are x = 108° and x = 72°
Well, the form 
gives the maximum (if a<0) at coordinates 
, where 
. If a>0, the same formula gives the minimum (there's no maximum)
