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:
[tex]a^2+b^2=c^2[/tex]
Plug in the given numbers (2), accordingly:
[tex]2^2+2^2=c^2\\4+4=c^2\\8 = c^2\\[/tex]
Take the square root of both sides:
[tex]\sqrt{8} =\sqrt{c^2}[/tex]
2.82 ≈ c
