Please mark me brainliest.
Sorry no I’m only in 8th :(
Sum of all exterior angle should be 360.
when the measure of each exterior angle is 36 then it has 10 sides and it is a

1. The angles DCA and BCA are the same.
2. Angles DCA and BCA are not supplementary. Since the both of them add up to 90° (we know that angle c is equal to 90° because in a right square all angles are 90°) the angles would be complementary, not supplementary. Supplementary angles add up to 180°
So you want to know how much was paid in total?
First, how much is 18% of 43?
43*0.18 =8.64
so the total prize will be the sum of the gratuty and the dinner prize: 43+8.64=51.64
and this is the solution!
