The answer to this question is
x = -15 + y
From picture we can see that there is a perpendicular bisector drawn on line KS.
Perpendicular bisectors of the sides of triangle are drawn to find the center of the circle which passes through corner points of the triangle.
Hence choice B) Circumcenter is correct.
2L + 2W = perimeter
dividing both sides by 2
L + W = (perimeter / 2)
Length = (perimeter / 2) -Width
Width = (perimeter / 2) -Length
Well I can’t draw anything out but the 15 foot ladder will be at a slant enough so she can reach the bulb. Yes she will be safe. Hope this helps. ;)
