Pls will give brainiest to best answer! kevin tries to climb a wall with a ladder. the length of the ladder is 15 feet and it reaches only 12 feet up the wall. what is the distance between the base of the ladder and the wall?

9.  15^2-12^2=81 the square root of 81 is 9

The equation a^2 + b^2 = c^2 can be used to find the length of the sides of any right triangle.
C= the side across from the right angle.
Knowing this, we can fill in the other side we know and then solve for the side that we don’t know.
(12)^2 + b^2 = (15)^2
144 + b^2 = 225
b^2 = 81
Now we take the square root of each side to get b alone
b = 9
9 feet is your answer.

The correct graph is the second one, with the points being at (-6,0), (2,0) and reaching down to (-2,-8)
