we know that
If line b is perpendicular to line a, and line c is perpendicular to line a,
then
line b and line c are parallel
and two lines parallel have the same slope
so
<u>Find the slope of the line b</u>
Let
The formula to calculate the slope between two points is equal to
substitute
therefore

<u>the slope of the line c is</u>
If a square-shaped pool with side lengths are 3a^5 then find the area of the pool
solution:
A = (3a^5) x (3a^5)
= 9a^5+5
= 9a^10
The area of the square-shaped pool are 9a^10 based on the given side length which is 3a^5
