A right triangle has hypotenuse of length c and two legs of lengths a and b, but these lengths are changing, in such a way that the triangle is still a right triangle as the side lengths change.

The length of the hypotenuse is increasing at a rate of 2cm/sec, and the length a is increasing at a rate of 4cm/sec. I think i understand how this question works. you need to use Pythagoras theorem
