Answer of the set is x=-11.2 and y=3
This property of addition is the Identity Property. The identity property states that any number added to 0 will equal to the original number.
Hope this helped☺☺
For a polygon,
the <span>Sum of Interior Angles = (Number of Sides -2) • 180 degrees
hexagon = 6 sides so
(6 -2) * 180
all angles sum to 720 So each angle = (720/6) = 120 degrees

Use Pythagoras theorem:
a^2 = b^2 + c^2
-15^2 + 18^2 = a^2
a^2 = 99
a = root of 99
50% of $730 is $365.
To find this answer, you simply divide 730 by 2.
Have a great day! :)
