Answer 1

Answer:

12 miles

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

let x be the distance from the Park to the Library, then

x² + 5² = 13²

x² + 25 = 169 ( subtract 25 from both sides )

x² = 144 ( take the square root of both sides )

x = $\sqrt{144}$ = 12

Answer 2

Answer:

12 mi.

Step-by-step explanation:

a^2+b^2=c^2

c is the hypotenuse (the line across the right angle) and a and b are the other sides.

a=5

c=13

Plug into the equation

5^2+b^2=13^2

b^2=169-25

b^2=144

b=12
