2 4/5= 14/5 1 3/9=12/9
14/5= 126/45 12/9=60/45
126/45+60/45=186/45
186/45= 4 6/45
Answer:
61
Step-by-step explanation:
The Pythagorean Theorem is a fundamental in geometry that involves looking at two sides of a right triangle and finding out the length of it. Let's use the formula with the corresponding numbers.
The formula for this question would be 
Since we know that a = 11 and b = 60, we can do the following and substitute :

11 squared is 121
60 squared is 3600
Now we need to add the two number together :
121 + 3600
3721
Since this number is under the square root, we have to square root it. :

61
Therefore c is equal to 61.
