<span>Let's assume the mat as a right triangle
Taking length of triangle be x
so height = x-21
and hypotenuse= x+6
for right triangle we can apply pythagoras theorem
so (x+6)^2=x^2+(x-21)^2
expanding we get
x^2 + 12 x + 36 = 2 x^2 - 42 x + 441
solving for x we get
x=9,45
But for length to be 9 height will be negative
So the length of mat will be 45 inches</span>
The point-slope form:
We have m = 2 and the point (1, 9).
Substitute:
5 divided by 8 = 0.63..
hope this helps! :)
