Question

the library is located 1.8 miles west of carllie house. the grocery is located 2.4 miles south of the library. what is the lengths of a straight line between carllie house and the grocery store

Answer 1

Hello!

You use the Pythagorean Theorem to solve this

$a^{2} + b^{2} = c^{2}$

c is the hypotenuse
a and b are bases

Put in the values you know

$1.8^{2} + 2.4^{2} = c^{2}$

Square the numbers

$3.24 + 5.76 = c^{2}$

Add

$9 = c^{2}$

Take the square root of both sides

3 = c

The answer is 3 miles

Hope this helps!
