Answer:
3240°
Explanation:
The formula for calculating the sum of the interior angles of a polygon is (n-2)x180 where n refers to the number of sides. Because we know that the polygon has 20 sides, the equation would be (20-2)x180. The answer would be 3240°.
You can solve this by substitution.
x+y=10
x-y=4
===== add the equations
2x=14
x=7
Then plug in x into one of the equations
7+y=10
y=3
so x^2=7*7=49
y^2=3*3=9
