1. If JK is formed by J(-7,-8) and K(1,4), determine if L(-9,5) lies on the perpendicular bisector.

L(-9,5)
R(1,4)
(-7,-8)
Part A
What elements do you need to show to confirm that Point L is on the
Perpendicular Bisector of JK?

step-by-stp

the correct answer is the section c

the first question mark is 6 and the second question mark is 26 (the square root)

step-by-step explanation:

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)

can i see a photo of the question so i can you?
