Answer 2

The equation is used to find the unknown length (a) will be 17² =15² + a². Then the correct option is A.

What is a Pythagoras theorem?

The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.

The Pythagoras theorem formula is given as

H² = P² + B²

A right triangle has a side with length 15 meters and a hypotenuse with length 17 meters.

The other side is labeled a.

17² =15² + a²

Then the correct option is A.
