Step-by-step explanation:
You used Pythagorean theroem which is correct as this does form a right triangle however 50 is the hypotenuse as the ladder is propped up against the wall. 30 would then be the height of the triangle and the base is unknown so...
50 squared minus thirty squared gives 1600 so:
Therefore x is the square root of 1600 which is 40
First, we need to move the decimal point directly in front of the repeating part. To do this, we need to move it two places to the right, which we can do by multiplying by 100.
100 × 0.2045454545 = 20.45454545
Now we need to subtract our original number.
Now we put that over 99 (that's one less than our 100 from earlier)
Our fraction is shaping up, but we shouldn't have a decimal in there. Let's multiply the top and bottom by 100 to get rid of it.
We're going to have to do some simplifying. (the top and bottom are both clearly divisible by 5 and then some)
