This question can be solved through algebric expression.
We know it is a right triangle and value of all sides given.
Formula = \(c^2\) = \(a^2\) + \(b^2\)
lengthy .
Follow this one:
we know both side must be equal.
Back solving strategy.
\(x^2\) + \((x+2)^2\) = \((2x-2)^2\)
Option A meets the condition.
A is the best answer.
