A 20-foot ladder leans up against the side of a building so that the foot of the ladder is 10 feet from the base of the building

harina [27]

Answer:

17.3

Step-by-step explanation:

To solve this equation, you need to use the pythagorean theorem which is:

$a^{2} +b^{2}= c^{2}$

a= length

b= height

c= hypotenuse

First, substitute in your values for the equation:

$10^2+b^{2} =20^{2}$

Then, use the squares in the equation:

$100+b^{2} =400$

Then, subtract 100 from both sides to isolate b:

$b^{2} =300$

Finally, square root both sides to get your answer:

$b=17.3205080757$

Then round to the nearest tenth which gives you 17.3.
