Answer:

16 feet

Step-by-step explanation:

The length of the ladder=20 feet

Distance from the base of the ladder to the house = 12 feet

You will notice that a wall is vertical and the ladder makes an angle with the horizontal ground(making it the hypotenuse). This is a right triangle problem.

To find the how far up the house can the ladder can reach, we simply find the third side of the right triangle.

From Pythagoras theorem

Hyp^2=Opp^2+Adj^2\\20^2=12^2+Adj^2\\Adj^2=400-144\\Adj^2=256\\Adj=\sqrt{256}=16

The third side of the right triangle is 16. Therefore the ladder leans 16 feet from the ground.

Answer:

16 feet

Step-by-step explanation:

the height of the ladder, the distance from the ladder base to the house and the height of the house the ladder will reach will form a triangle, as shown in the image.

To know the height of the house the ladder will reach, we just need to use Pythagorean theorem. Being h the house's height we want, we have:

20^2 = 12^2 + h^2

h^2 = 400 - 144 = 256

h = 16 feet.

Select the point that satisfies
Vika [28.1K]

Answer:

A. (5,5)

Step-by-step explanation:

  1. Plug in (5,5) for the x and y values according to the ordered pair. In this case the equation should turn out like this :5 ≤ 5²- 4(5) + 2
  • Simplify the equation : 5 ≤ 25 - 20 + 2
  • 5 ≤ 7
  • A is the answer because it satisfies the inequality as 5 is less than or equal to seven. Though, in this case it is just less than, but not equal to.
