Question

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

A triangle has side lengths 18, 24, x.
18 + 24 = x
18 squared + 24 = x
(18 + 24) squared = x squared
18 squared + 24 squared = x squared

Answer 1

Answer:

18 squared + 24 squared = x squared

Step-by-step explanation:

As we know from Pythagorean theorem:

a^2=b^2+c^2, where a -s hypotenuse and b&c are adjacent sides of right angle.

Here we should have: x^2=18^+24^2

Last line is the correct option
