Question

What is the third side

Answer 1

Answer:

A. 2.82 m

Step-by-step explanation:

The missing side we are trying to find is the hypotenuse, this is because it is the longest side of a right triangle.

The Pythagorean Theorem is used:

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

Plug in the given numbers (2), accordingly:

$2^2+2^2=c^2\\4+4=c^2\\8 = c^2$

Take the square root of both sides:

$\sqrt{8} =\sqrt{c^2}$

2.82 ≈ c
