Question

Which equation can be used to find x,the length of the hypotenuse of the right triangle

Answer 1

a^2 + b^2 = c^2...a and b are the legs and c is the hypotenuse
18^2 + 24^2 = x^2 <==

** the hypotenuse is always the longest side..it is the side opposite the right angle

Answer 2

Answer:

$x^{2}=24^{2}+18^{2}$

Step-by-step explanation:

we know that

The Pythagoras Theorem states that in a right triangle

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

where

c is the hypotenuse

a,b are the legs of the right triangle

In this problem we have

$a=24\ units, b=18\ units, c=x\ units$

substitute

$x^{2}=24^{2}+18^{2}$
