The distance between the Library and Sophia's house is 9.43 miles. The answer is arrived at using the Pythagorean Theorem.
What is the Pythagorean Theorem?
The Pythagorean Theorem indicates the sum of the square of the sides of all sides of a right-angled triangle is equal to the square on the hypotenuse. That is:
a² +b² = c².
That is assuming the Hypothenus is c, then the formula for finding its length will be:
c = √(a²+b²).
Solution
From the question, we can see that:
- the height of the triangle plotted on the graph (see attached image) is 8 miles between (6,1 ) and (6,9);
- The base of the triangle plotted on the graph is 5 miles between (6,1) and (1,1).
To arrive at the Hypothenus (which is the distance between the library and Sophia's house) we say:
H = √(8²+5²)
= √(64+25)
= √89
= 9.43 miles.
