Question

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

Answer 1

Answer:

Explanation:

For any right triangle, the longest side is called the hypotenuse. Therefore, by Pythagorean theorem it is true that:

$x^2=a^2+b^2$

Where:

x: Hypotenuse

a, b: The other two sides.

For instance, if we have a right triangle whose sides measure:

$a=3 \\ \\ b=4$

Then, the hypotenuse can be found as:

$x=\sqrt{3^2+4^2} \\ \\ c=\sqrt{25} \\ \\ c=5$

Answer 2

Answer is D. Don't know why there isn't any right answers anywhere else.
