dimulka [17.4K]

Answer:

8 ft

Step-by-step explanation:

the ladder will make a right angle triangle with the house. The hypotenuse of the triangle is the ladder, 20 ft, and the height of the triagnle is 18 ft.

Solve for the base of the right angle triangle using pythagorean's theorem:

c=20, a=18, b=?

b^{2}=c^{2} - a^{2}\\b^{2}=20^{2} - 18^{2}

b=\sqrt{72}

b= 8.49 ft

round to the nearest foot,

What is the formula of 20 is 4% of what number. How do you get the whole number
lutik1710 [3]

Well we know 4% is just 4/100.

So 20 = 4/100.

Let's find out what 1/100 is and multiply that by 100:

20/4 = 5.

So 1/100 = 5.

5*100 = 500.
