Step-by-step explanation:
Hello, I’m here to help you! 
➡ Pythagorean Theorem: a² + b² = c² 
➡ We eliminate D - So the Pythagorean theorem is used for right triangles and that equation is a² + b² = c² and answer D doesn't have anything squared. 
➡ Hypotenuse is what letter in the theorem? It is Letter C! 
➡ 11² + 60² = 3721 
The correct Option is C. 
Hope this helps! :)
