The ladder makes a rectangle triangle with the floor and wall, the ladder is the hypothenuse. So we use Pythagoras theorem: <span>the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides
</span>So we have:
hyp^2 = wall^2 + floor^2
and plugging data in:
18^2 = wall^2 + 7^2
324 = wall^2 + 49
wall^2 = 275
<span>wall = 16.58
</span>
Step-by-step explanation:
step 1. x = .484848 . . . repeats
step 2. 100x = 48.48484848 . . . (multiply by 100)
step 3. subtract x from 100x : 99x = 48
step 4. x = 48/99 (now add the 2 back in)
step 5. answer: 2-48/99.
