Answer: 37
Step-by-step explanation:Using the Pythagorean Theorem, a ² + b ² =c ², you substitute the values for a and b with 12 and 35. This makes your equation 12 ² +35 ² = c ² . You then add 12 ² with 35 ² and that gives you 37 ² = C ² . You find the square root of both sides which is 37=C, giving you the length of C.
