Answer:

12 ft

Step-by-step explanation:

You have a right triangle with the hypotenuse = 13 and one leg = 5

Let x = distance above the ground that the ladder touches the wall

Now use the Pythagorean theorem

x^{2}  + 5^{2} = 13^{2} \\x^{2}  + 25 = 169\\x^{2}  = 144\\x = \sqrt{144} = 12

It looks like none of the choices are correct, because the answer is 12 ft.

By the way, it is impossible for the ladder to reach up the wall a distance longer the the length of the ladder.  Think about it.  OK?

Which statement correctly describes the location of the incenter of a triangle?
NemiM [27]

9514 1404 393

Answer:

  B)  The incenter is equidistant from all three sides of the triangle.

Step-by-step explanation:

The incenter is the center of the inscribed circle, which is tangent to all three sides. Hence, the distance from the incenter to each side is the radius of the circle. The incenter is equidistant from the sides of the triangle.
