Aright triangle has a hypotenuse c = 12.6 and a leg b = 8.5. what is the approximate length of leg a?

This problem can use the Pythagorean theorem of c2 = a2 + b2 where c is the length of the hypotenuse, b is the length of the longer side and a is the length of the shorter side. Plugging in the values of c and b 12.6^2 = 8.5^2 + a2, the value of the shorter side is equal to 9.3.

i do not know the answer bro
