Ax^2+bx+c=0 is the standard form, so we add 5 to both sides to get
1*x^2+(-10)x+21=0
The intersection of the perpendicular bisector of GF and the angle bisector of ZE inside the quadrilateral.
What is a quadrilateral?
quadrilateral is a plane mathematical closed figure consist of four side and four edges. There are 7 types of quadrilateral
a) Trapezium,
b) Parallelogram,
c) Rectangle,
d) Rhombus,
e) Square,
f) Kite
as the given figure is unknown with dimension it is difficult to find the measurement but it is be to noted that the perpendicular bisector of GF and angle bisector of angle E will intersect at some point inside the given quadrilateral.

Answer:
True
Step-by-step explanation:
If the triangle was a right angled triangle then we can prove it using the Pythagoras theorem: c² = a² + b²
c is the largest side and a and b are the two smaller sides of the triangle.
So if this is true then √72² + 154² should be 170:
170² = 72² + 154²
28900 = 5184 + 23716
28900 = 28900
So we have proved using Pythagoras theorem that the triangle is a right angled triangle.
