Pentagon has 5 sides
The formula for finding the sum of the measure of the interior angles is (n - 2) * 180
(5-2)×180= 3×180=540
To get each interior angles
540/5 = 108
180 -108 = 72
To get x
72+72+x= 180 (sum if angles in a triangle)
144+x= 180
x = 180 -144 = 36
2. x is part of the interior angles = 108
27 ÷ (-2 + (-7))
27 ÷ (-9)
-3
The answer is -3. Hope that helps!
By the Intersecting Secants Theorem we have
2x(2x+7)=x(x+23)
4x^2+14x=x^2+23x
3x^2=9x
3x=9
x=3
Since DY is length 2x,
the length of DY is 6.
