Step-by-step explanation:
13x+4y=487------>13x+4y=487----------->13x+4y=487
6x+2y=232-------->-2(6x+2y)=232*-2---->-12x-4y=-464
x=23----> 6(23)+2y=232------->138+2y=232----->2y=94--->y=47
x=ties y=suspenders
The formula for sum of the interior angles is,
S = 180 x (n - 2)
and that of the number of diagonals is,
d = n x (n - 3) / 2
where n is the number of sides. For 6-sided polygon,
S = 180 x ( 6 - 2) = 720
d = 6 x (6 - 3) / 2 = 9
Therefore, the answer is 720 degrees and 9 diagonals.
