The sum of the inner angles of a polygon with n sides is
Since your polygon has 6 sides, the sum of its inner angles has to be
On the other hand, the sum of its inner angles is
And it has to be 720, so we have
9) x.14 = 6.26 ==> 14x=156 ==> x=11.1
12) OAB = Right Triangle : (27+24)² = 24² + AB² (Pythagoras)
==> 51² =24² + AB² ==> 2,601 = 576 + AB² ==> AB² = 2,601 - 576 = 2,025
==> AB² = 2015 AND AB =√2025 = 45

The equation of the parabola that similar to f(x) = but the vertex is (3, 5) in the standard form is y = + 5
The equation of the parabola
f(x) =
The standard vertex form of a parabola is
y = + k
The coordinates of the vertex of a parabola = (3, 5)
Where (h, k) is the coordinates
From the given function of the parabola f(x) =
The value of a = 7
Substitute the values in the vertex form of a parabola
y = + 5
Hence, the equation of the parabola that is similar to f(x) = but the vertex is (3, 5) in the standard form is y = + 5
