Answer:
Step-by-step explanation:
So we just want to get y by itself
2x - 4y = 8
4y = 2x - 8
y = (2/4)x - 2
y = (1/2)x - 2
In this form the y intercept and slope are easy to see. the slope is m and y intercept is b.
slope = 1/2
y intercept = -2
The answer is that CG is equal to 13cm.
As given that DG, EG, and FG are perpendicular bisectors of the sides of triangle ABC and it shows that G is the point of intersection and also it is the circumcenter of the triangle, So;
AG = BG = CG
By Pythagorean theorem
BG² = DG² + BD²BG²
And DG = 5cm and BD = 12cm
So,
BG = √(DG² + BD²) = √(5² + 12²) = √(25 + 144) = √169 = 13
BG = 13 = AG = CG
Thus,
CG = 13cm
