Answer:

b / (a+c)  * b / (a-c) = -1

Step-by-step explanation:

Perpendicular lines have slopes that multiply to -1

The slope of AC is

(b-0)/(a- -c)

b / (a+c)

The slope of BC is

(b-0)/(a -c)

b / (a-c)

If the lines are perpendicular then the slopes multiply to -1

b / (a+c)  * b / (a-c) = -1

Answer:

First one

Step-by-step explanation:

Angle ACB = 90

mAC × mBC = -1

(b-0)/(a+c) × (b-0)/(a-c) = -1

b/(a-c) × b/(a+c) = -1
