Answer:
x = 8mi
Explanation:
Use Pythagorean theorem! It states that you can find any side of the triangle using the equation
+
=
. The sides a and b are the sides that are shortest, and c is the longest/slanted side (hypotenuse). So plug in what they give you to get
+
=
( a and b can be used for either number that is not the hypotenuse). A little bit of basic algebra will lead you to get x=8 mi.
algebraic steps:
+
=
+
=
+ 36 = 100
= 64
a = 8mi
