How do you solve for missing leg of the pythagorean theorem

If you are solving for the hypotenuse, use
a² + b² = c²

if you are solving for a side, use
c² - a² = b²

hypotenuse = c
other sides = a, b

hope this helps

Answer: the correct answer is 10step-by-step explanation: let the number be n, then the expression becomes,then“twelve more than the quotient of a number and two, decreased by four” iswhen n=4,we substitute 4 whetever we see n to get,we simplify to obtain,we further simplify to get,therefore the correct answer is c.
