Answer: (6 x 2) - (4 x 5) + (12 / 4)
a²+ b² = c² is the formula for pythagorean theorem.
it is used to find out the hypotenuse(the side opposite the 90° angle) of a right angled triangle.
the two sides adjacent to the 90° angles are 'a' and 'c'. the theory is that if you add the squares of a and b, the hypotenuse is equal to c².
