If you continue the line of the second step (from the top), you will get a parallel to the floor which will also equal to 4 feet.
Now the right triangle just created has one leg = 4 feet and another = 3 feet.
Calculate the hypotenuse (Railing) using Pythagoras;
(Railing)² = 4² + 3²
((Railing)² = 4² + 3²
Railing)² = 16 + 9 =25
(Railing)² = 25 and Railing = √25 = 5
The answer would be 7 out of 20 or 7/20 because 6 pennies +3 dimes +4 quarters =13 coins so that leaves 7 nickels
The formula you need to use is a^2 + b^2 = c^2. A is the side of 3 and B is the side of 7, so 3^2 + 7^2 = c^2.
9 + 49 = c^2
58 = c^2
√58 = C
So your answer is C. √58. I hope this helps!
